	* app/Makefile.am
	* app/sanity.[ch]: new files implementing sanity_check() for
	run-time checking library versions. Added a check for FreeType but
	disabled it until we figured if and how freetype causes some of
	the DLL hell bugs.

	* app/main.c (main): call it and abort if it fails.

	* app/app_procs.[ch]: added app_gui_abort() so main.c doesn't
	need to #include "gui/gui.h"

	* app/gui/gui.[ch] (gui_libs_init): removed library sanity checking.

	(gui_abort): new function which shows the abort message.
