[evolution-patches] 72088, force loading some types in calendar a11y code

[Harry Lu <Harry Lu Sun COM>]

JP and Rodrigo,
   When I run CVS head version of evolution, I found some calendar a11y 
functions don't work. There are also some warnings in the output:
(evolution-2.2:31757): GLib-GObject-WARNING **: gsignal.c:1019: unable 
to lookup signal "event" of unloaded type `EText'
(evolution-2.2:31757): GLib-GObject-CRITICAL **: file gsignal.c: line 
822 (g_signal_add_emission_hook): assertion `signal_id > 0' failed

(evolution-1.2:31757): GLib-GObject-CRITICAL **: file gsignal.c: line 
822 (g_signal_add_emission_hook): assertion `signal_id > 0' failed

   As I checked, this might due to the changes in gobject. Some object 
types are not loaded when we use them.
   Here is a patch to force loading some types. Please review it.
   Thanks!
      Harry
