	Made plug-ins honor the current GIMP theme:

	* app/core/gimp.[ch]: added GimpGetThemeDirFunc to the GUI vtable.

	* app/gui/gui-vtable.c: implement it here.

	* tools/pdbgen/pdb/gimprc.pdb: added new PDB function
	gimp_get_theme_dir().

	* libgimp/gimpui.c: use the new function and fall back to
	gimp_gtkrc() if it returns NULL.

	* app/pdb/gimprc_cmds.c
	* app/pdb/internal_procs.c
	* libgimp/gimpgimprc_pdb.[ch]: regenerated.

	* app/gui/themes.c: unrelated cleanup.
