Improvements/fixes to app deregistration (but some still are pending).

Started adding support for StateSet and RelationSet on Accessibles.
Added deregistration on app exit to the atk bridge.

+
+       * libspi/accessible.c:
+               Stubbed-in the implementations for
+                       Accessibility_Accessible_getState and
+                       Accessibility_Accessible_getRelationSet.
+       * libspi/registry.c:
+               Improved de-registration process and fixed some bugs, 
+                       deregistration should work correctly
+                       once the compare_object_func()'s CORBA_Object_hash
+                       usage is fixed (currently still broken).
+               (Probably the event listener registration still needs
+                       fixing.)
+       * libspi/desktop.c:
+               Added initialization of applications list (to NULL).
+       * util/magnifier.c:
+               Reduced speech compression from 0.5 to 0.7, for demo.
+               Changed call to gdk_window_set_decorations()
+                       to gtk_window_set_decorated().
+       * at-bridge/bridge.c:
+               Bridge now deregisters when app exits, via
+                       registration of a cleanup function
+                       with the g_atexit() call.
+                       Required making 'app' static, renamed 'this_app'.
+               Fixed broken use of bonobo_init, passing argv wrongly.
