removed the gimp_busy boolean, check whether user_installation is needed

2001-07-10  Michael Natterer  <mitch@gimp.org>

	* app/app_procs.[ch]: removed the gimp_busy boolean, check whether
	user_installation is needed here, not in user_install.c, parse
	gtkrc an friends only if(!no_interface), create the Gimp object
	before parsing gimp's rc files an pas it to the parse functions,
	many other cleanups.

	* 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]: added EEKy wrappers for all gimp_unit_*()
	functions which are used by widgets.

	* app/main.c: cleaned up the global variables, removed the fatal
	message handler, call app_init() directly, not via the
	user_install stuff, misc. cleanups.

	* app/user_install.[ch]: removed the check if user_installation is
	needed (done by app_procs.c now).

	* app/core/gimp.[ch]: added the user_unit list and the "busy"
	boolean. Moved gimp_[set|unset]_busy() here. Added
	gimp_initialize() which is called after unitrc and gimprc are
	parsed.
