	Cleaned up and improved the message system:

	* app/core/gimp.[ch]: added "const gchar *domain" to
	GimpMessageFunc (a NULL domain means the message is from the GIMP
	core, everything else is a plug-in).

	* app/errors.c: pass "domain == NULL" to gimp_message().

	* tools/pdbgen/pdb/message.pdb: derive the message domain from the
	current plug-in's menu_path (evil hack but works reasonably well).

	* app/pdb/message_cmds.c: regenerated.

	* app/widgets/gimpwidgets-utils.[ch] (gimp_message_box): added a
	header showing the message domain and changed the dialog layout to
	follow the HIG more closely.

	* app/gui/error-console-dialog.[ch]: removed.

	* app/widgets/gimperrorconsole.[ch]
	* app/gui/error-console-commands.[ch]
	* app/gui/error-console-menu.[ch]: new files containing a
	re-implementation of the error console dialog.

	* app/gui/Makefile.am
	* app/gui/dialogs-constructors.c
	* app/gui/gui.c
	* app/gui/menus.c
	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h: changed accordingly.

	* app/display/gimpprogress.c: added more spacing and removed the
	separator (more HIG compliant).

	* plug-ins/[most plug-ins].c: Changed lots of messages and
	progress strings:

	- Removed plug-in names from messages since that's automatically
	  covered by "domain" now.
	- Put all filenames in ''.
	- Changed "Loading" to "Opening".
	- Added "..." to all progress messages.
	- Cleaned up all file open/save error messages to look the
	  same and include g_strerror(errno).
	- Removed special casing for progress bars and *always* show them,
	  not only if run_mode != GIMP_RUN_NONINTERACTIVE (we can't expect
	  all plug-ins to do this correctly but need to hack the core to
	  sort out unwanted progress bars).

	Unrelated:

	- Cleaned up indentation, spacing, #includes, coding style and
	  other stuff while I was at all these files.
