2005-08-02  Michael Natterer  <mitch@gimp.org>

	* plug-ins/dbbrowser/Makefile.am
	* plug-ins/dbbrowser/gimpprocbrowser.[ch]
	* plug-ins/dbbrowser/gimpprocview.[ch]: removed these files...

	* libgimp/Makefile.am
	* libgimp/gimpui.h
	* libgimp/gimpui.def
	* libgimp/gimpprocbrowserdialog.[ch]
	* libgimp/gimpprocview.[ch]: ...and added them here. Turned the
	procedure browser into a widget called GimpProcBrowserDialog and
	changed its API completely. Fixes bug #165009.

	* plug-ins/dbbrowser/plugin-browser.c
	* plug-ins/dbbrowser/procedure-browser.c
	* plug-ins/script-fu/Makefile.am
	* plug-ins/script-fu/script-fu-console.c: changed accordingly.

	* plug-ins/pygimp/Makefile.am
	* plug-ins/pygimp/procbrowser.c: ditto (#if 0'ed stuff so it compiles).
