	Got rid of the last global variables except the_gimp:

	* app/Makefile.am
	* app/appenv.h: removed this file.

	* app/errors.[ch] (gimp_errors_init): new function which lets the
	error system know about "full_prog_name", "stack_trace_mode" and
	"debug_handlers". Remember these values privately.

	* app/app_procs.[ch] (app_init): added "full_prog_name" and
	"stack_trace_mode" parameters here too.

	* app/main.c (main): call gimp_errors_init() and pass the
	additional parameters to app_init().
