	* app/channel_ops.[ch]: new ui for the "Layer Offset" dialog.

	* app/channels_dialog.c
	* app/layers_dialog.c: major code cleanup: Folded some callbacks
	into common ones, "widget" instead of "w", indentation, ...

	* app/commands.c
	* app/interface.[ch]
	* app/global_edit.c: the query boxes must be shown by the caller
	now. There's no need to split up the string for the message box
	manually as the Gtk 1.2 label widget handles newlines corectly.
	Added the "edge_lock" toggle to the "Shrink Selection" dialog.
	Nicer spacings for the query and message boxes.

	* app/ink.c: tried to grab the pointer in the blob preview but
	failed. Left the code there as a reminder (commented out).

	* app/menus.c: reordered <Image>/Select.

	I was bored and grep-ed the sources for ancient or deprecated stuff:

	* app/about_dialog.[ch]
	* app/actionarea.[ch]
	* app/app_procs.c
	* app/brush_edit.c
	* app/brush_select.c
	* app/color_select.c
	* app/convert.c
	* app/devices.c
	* app/gdisplay.c
	* app/gdisplay_ops.c
	* app/histogram_tool.[ch]
	* app/info_window.c
	* app/install.c
	* app/ops_buttons.c
	* app/palette.c
	* app/palette_select.c
	* app/paths_dialog.c
	* app/pattern_select.c
	* app/resize.c
	* app/scale_toolc.c
	* app/text_tool.c:
	s/container_border_width/container_set_border_width/g,
	s/sprintf/g_snprintf/g, replaced some constant string lengths with
	strlen(x).

	* app/bezier_select.c
	* app/blend.c
	* app/boundary.c
	* app/errors.[ch]
	* app/free_select.c
	* app/gimpbrushlist.c
	* app/gimprc.c
	* app/iscissors.c
	* app/main.c
	* app/patterns.[ch]
	* app/text_tool.c: namespace fanaticism: prefixed all gimp error
	functions with "gimp_" and formated the messages more uniformly.

	* app/gradient.c
	* app/gradient_select.c: same stuff as above for the ui
	code. There are still some sub-dialogs which need cleanup.

	Did some cleanup in most of these files: prototypes, removed tons
	of #include's, i18n fixes, s/w/widget/ as above, indentation, ...
