Exposes a new variables that references all the active Timeouts and Idle handlers to avoid collection/ * glib/Timeout.cs: Implement TimeoutProxy that acts as a filter to remove the proxy when the timeout is removed. Register a TimeoutProxy when we create a timeout. * glib/Idle.cs: Implement IdleProxy that acts as a filter to remove the proxy when the idle handler is removed. Register an IdleProxy when we create a timeout. svn path=/trunk/gtk-sharp/; revision=34094
