	Added some basic CORBA stuff. CORBA is only used in plugins, but
	we need to initialize it in the main program.

	* configure.in (--enable-orbit): New parameter to link with ORBit.
	If found, check for LibGnorba and define two (HAVE_OBIT) and
	(HAVE_LIBGNORBA) automake conditionals. Also AC_DEFINE(HAVE_ORBIT)
	and AC_DEFINE(HAVE_LIBGNORBA) if ORBit/LibGnorba is found.
	Only check for this if the GModule Plugins are enabled.

	* src/Makefile.am (CPPFLAGS): Define `_IN_GEDIT'.
	(gedit_LDADD): Link with ORBit and LibGnorba if they're found.

	* src/gE_plugin.c (gE_Plugin_Load): Pass the edit context to
	the plugin so that it can use the old plugin API as well.

	* src/gE_plugin.h: If we are not _IN_GEDIT, add `extern' declarations
	for the CORBA variables `global_orb', `root_poa', `root_poa_manager',
 	`global_ev' and `name_service' and a prototype for `corba_exception'.

	The following stuff is `#ifdef HAVE_LIBGNORBA':

	* src/gedit.c (corba_exception): New function which is used for
	CORBA error handling.
	(global_orb, root_poa, root_poa_manager, global_ev, name_service):
	New global variables which can be used in CORBA-aware plugins.
	(main): Initialize CORBA here.
