	* app/gimpui.[ch]
	* app/preferences_dialog.c: removed & renamed some functions from
	gimpui.[ch] (see below).

	* libgimp/Makefile.am
	* libgimp/gimpwidgets.[ch]; new files. Functions moved from
	app/gimpui.[ch]. Added a constructor for the label + hscale +
	entry combination used in many plugins (now hscale + spinbutton).

	* libgimp/gimpui.h: include gimpwidgets.h

	* plug-ins/megawidget/megawidget.[ch]: removed all functions
	except the preview stuff (I'm not yet sure how to implement this
	in libgimp because the libgimp preview should be general enough to
	replace all the other plugin previews, too).
