Fix bug 6613 (no way to delete files without using trash) by
	integrating Maciej's patch to add an optional Delete command (with
	some fixes to the patch). There may still be some loose ends.

	Fix bug 2206 (No way to move or copy a file to a different
	directory from keyboard) by implementing Cut, Copy, and Paste for
	files, in a way that will be familiar to Windows users. The
	positioning of the new files is not right yet (they inherit their
	position from the old files), there is no feedback when you have
	cut some files (Arlo's idea, which I might implement, is to make
	them translucent to show they are "on the way out") or when you
	have copied some files, and I think there are some other loose
	ends.

	Fixed cut, copy, and paste within the file names when you do a
	rename. This wasn't working at all.

	Got rid of configure-time checks that were looking at the
	existence of some special system files.

	Fixed a few minor bugs discovered by code inspection.

	* libnautilus-extensions/nautilus-global-preferences.h:
	* libnautilus-extensions/nautilus-global-preferences.c:
	(global_preferences_install_descriptions),
	(global_preferences_install_defaults),
	(global_preferences_install_visibility),
	(global_preferences_create_dialog): Add expert preference to add a
	Delete command that bypasses the Trash.
	* src/file-manager/nautilus-directory-view-ui.xml: Add Delete, Cut
	Files, Copy Files, and Paste Files.
	* src/file-manager/fm-directory-view.c: (confirm_delete_directly),
	(delete_callback): Add delete code.
	(bonobo_menu_empty_trash_callback): Get rid of extraneous cast.
	(fm_directory_view_initialize): Track the delete preference. Set
	the flags properly to indicate we have our own X window. Add a
	target so GTK knows that we accept pastes of copied files.
	(forget_clipboard_contents): Helper for when we are no longer the
	clipboard owner.
	(fm_directory_view_destroy): Remove the delete preference
	callback. Free the clipboard contents.
	(offset_drop_points): Change so it handles NULL for the list of
	points.
	(trash_or_delete_files_common): Remove unneeded parameters.
	(get_current_event_time): New function, placeholder that just
	returned GDK_CURRENT_TIME. Perhaps we should get the real event
	time here for use in clipboard manipulation calls.
	(copy_or_cut_files): New function. Save the selection for later
	use in a paste.
	(copy_files_callback), (cut_files_callback): Call the new
	copy_or_cut_files function.
	(paste_files_callback): Do the clipboard convert that results in
	the paste operation.
	(real_selection_clear_event): Forget the clipboard contents.
	(real_selection_get): Convert the selection into the appropriate
	format and put it on the clipboard.
	(convert_lines_to_str_list): Helper function for decoding incoming
	pasted files.
	(real_selection_received): Handle pasted files by parsing and then
	triggering a file copy operation.
	(real_merge_menus): Add verbs for cut, copy, and paste.
	(enable_delete_changed_callback): Keep track of delete command
	status in a boolean.
	(real_update_menus): Show delete command if the preference is on
	and we are not showing "Delete from Trash". Update names of the
	Cut and Copy command depending on how many files are selected.
	Also desensitize them when none are selected.
	(fm_directory_view_select_file): Initialize an uninitialized field.
	(fm_directory_view_move_copy_items): Allow relative_item_points to
	be NULL.
	(real_realize): Create our own X window.
	(real_size_allocate): Trick GtkScrolledWindow into doing the right
	thing despite the fact that we have our own X window.
	(fm_directory_view_initialize_class): Moved down to the bottom so
	we don't need so many forward declaractions. Added code to set up
	some needed atoms and new default handlers.

	* libnautilus-extensions/nautilus-icon-text-item.c:
	(send_focus_event), (iti_stop_editing), (iti_start_editing): Add
	code to send the appropriate focus events to the fake off-screen
	GtkEntry. This makes the clipboard code that tracks focus-related
	signals work properly with this entry.
	(iti_event): Tweak the sequence and simplify the code a bit.
	* libnautilus/nautilus-clipboard.c:
	(set_paste_sensitive_if_clipboard_contains_data): Add more
	FIXMEs. This function is very far from useful, and it's not clear
	that it can be implemented efficiently under X.
	(nautilus_clipboard_set_up_editable): Get rid of silly
	"grab_focus" hack that was an attempt to address the problems with
	the NautilusIconTextItem. The real solution was to do focusing for
	that item too.
	(nautilus_clipboard_set_up_editable_in_control): Fix this so it
	works when called on an editable that is already focused.
	* src/file-manager/fm-icon-view.c: (renaming_icon_callback): Get
	rid of "grab_focus" workaround, which wasn't working.

	* acconfig.h:
	* configure.in:
	Remove all configure checks that were checking the existence of
	files.
	* libnautilus-extensions/nautilus-medusa-support.c:
	(nautilus_medusa_check_cron_is_enabled): Simplify logic so there's
	less room for confusion (I did this as a fix for the bug that was
	reported on the mailing list, but Rebecka checked in the small
	patch first). Also change it so we don't need a configure-time
	check for the existence of the process directory and fix it so we
	won't get a core dump if the file doesn't have a space character
	in it. Also change the logic so we don't leave the directory open
	when we do find the cron process.
	* libnautilus-extensions/nautilus-volume-monitor.c:
	(nautilus_volume_monitor_initialize_class),
	(has_removable_mntent_options),	(get_removable_volumes),
	(volume_is_removable), (volume_is_read_only),
	(mount_volume_get_cdrom_name), (mount_volume_activate_cdda),
	(mount_volume_activate_cdrom), (build_volume_list_delta),
	(get_current_mount_list), (mount_lists_are_identical),
	(verify_current_mount_state), (mount_volume_floppy_add),
	(get_cdrom_type_solaris), (mount_volume_iso9660_add),
	(display_mount_status), (close_error_pipe),
	(nautilus_volume_monitor_mount_unmount_removable),
	(mount_volume_add_filesystem): Make changes throughout to get rid
	of dependence on configure-time file checks and do things at
	runtime instead. Also use typedefs to make less code conditional.
	Also fix the Solaris CD-ROM code which was casting a GString to
	a (char *) before, so it used absurd file names, and failed to open
	and returned FALSE all the time.

	* libnautilus-extensions/nautilus-icon-container.c:
	(nautilus_icon_container_start_renaming_selected_item): Send the
	renaming signal before setting up the rest of the icon. This
	change is not really needed, but it's a better order to do things.

	* libnautilus/nautilus-clipboard-ui.xml: Move tips into the
	commands instead of the menu items (for style mostly, no practical
	implications at the moment).
	* src/nautilus-shell-ui.xml: Remove tips from Cut, Copy, and Paste,
	since tips from insensitive items aren't used, and if we had tips,
	we'd put them on the command, not the menu item, anyway.
