	Changed:-

	* app/dialog_handler.c
	* app/dialog_handler.h
	* app/gimage.c
	* app/gimprc.c
	* app/plug_in.c
	* app/plug_in.h

	Fixed problem with TAB key hiding all dialogs. With some WM
	you could hide all the windows with TAB then close the last image
	down... opps how do you get back to the main dialog. Main
	dialog is now poped up when last image is closed and we had
	used TAB key to hide it.

	New PDB functions to query plugin info. Plugin to follow...
