* glib/Source.cs: Add new base class to hold the method to be
	called, and the proxy handler we use to keep references to them
	and avoid a collection.

	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.
