	Make message dialogs transient for the progress window.
Addresses
	bug #347214.

	* app/core/gimp-gui.[ch]: added a progress parameter to
	gimp_message().  Let gimp_message() deal with optionally
	delegating the message to gimp_progress_message().

	* app/errors.c: changed accordingly.

	* app/core/gimpprogress.[ch] (gimp_progress_message): return a
	boolean indicating whether the message was handled.

	* app/gui/Makefile.am
	* app/gui/gui-message.[ch]
	* app/gui/gui-vtable.c: moved message handling to a new file.
Only
	use the global error dialog for messages without a progress.
	Otherwise attach an error dialog to the progress and try to make
	it transient to the progress window.

	* tools/pdbgen/pdb/message.pdb:
	* app/plug-in/gimpplugin-progress.[ch]: don't delegate messages
to
	the progress interface, this is handled by gimp_message() now.

	* app/pdb/message_cmds.c: regenerated.

	* app/plug-in/gimpplugin.c
	* app/actions/documents-commands.c: formatting.
