Sven Neumann 073e533a8a Finally landed the new GimpConfig based gimprc parser. It's not finished 
2002-11-18  Sven Neumann  <sven@gimp.org>

	Finally landed the new GimpConfig based gimprc parser. It's not
	finished yet but we need to start somewhere. This release removes
	the old gimprc.[ch] files. The gimprc format changes slightly, but
	the changes are minimal. The Preferences dialog is temporarily
	disabled since it still needs to be ported. If you are are afraid,
	stay away from CVS for a few days ;-)

	* app/Makefile.am
	* app/gimprc.[ch]: removed the old gimprc system.

	* app/base/Makefile.am
	* app/base/base-config.[ch]: removed these files in favor of
	config/gimpbaseconfig.[ch].

	* app/core/Makefile.am
	* app/core/gimpcoreconfig.[ch]: removed these files in favor of
	config/gimpcoreconfig.[ch].

	* app/config/Makefile.am
	* app/config/config-types.h: moved typedefs into this new file.

	* app/config/gimpbaseconfig.[ch]
	* app/config/gimpcoreconfig.[ch]
	* app/config/gimpdisplayconfig.[ch]
	* app/config/gimpguiconfig.[ch]
	* app/config/gimprc.[ch]
	* app/config/test-config.c: brought into shape for real use.

	* app/base/base-types.h: include config/config-types.h here. Added
	a global GimpBaseConfig *base_config variable to ease migration.

	* app/gui/Makefile.am: temporarily disabled the preferences dialog.

	* app/app_procs.c
	* app/undo.c
	* app/undo_history.c
	* app/base/base.[ch]
	* app/base/gimphistogram.c

	instead of the old gimprc stuff.

	* etc/gimprc.in
