	* app/gimpui.[ch]: removed the query boxes.

	* po-libgimp/POTFILES.in
	* libgimp/Makefile.am
	* libgimp/gimpui.h
	* libgimp/gimpquerybox.[ch]: new files. Added a boolean query box
	to get rid of all those handmade "yes/no" query dialogs. Changed
	the query box callback prototypes to return the entered value
	instead of a pointer to it.

	* app/commands.c
	* app/display_ops.c
	* app/gradient.c
	* app/palette.c
	* app/paths_dialog.c: correctly call the new query box functions
	and use the boolean query box instead of inventing this wheel over
	and over again.

	* app/global_edit.[ch]: same as above and cleaned up the public
	interface.
