	* app/app_procs.[ch]: removed the gimp_busy boolean, check whether
	user_installation is needed here, not in user_install.c, parse

	* app/appenums.h: added MessageHandlerType and StackTraceMode.

	* app/appenv.h: removed MessageHandlerType, declare all global
	variables from main.c (no more hidden global stuff please).

	* app/errors.[ch]: added the fatal message func here (from main.c),
	removed the StackTraceMode enum.

	* app/gimprc.[ch]: renamed functions to gimprc_*(), pass a Gimp
	pointer to some functions.

	* app/gimpunit.c
	* app/unitrc.h: ok, this is ugly: renamed all functions to
	_gimp_unit_*() and made them public. The unit list is part
	of the Gimp object now, so pass a Gimp* to all functions.

	* app/libgimp_glue.[ch]: ...
