Add symbolic constants for event emission control

Browse Source 
Similar to https://bugzilla.gnome.org/show_bug.cgi?id=631413 in GLib,
GTK+ should have symbolic constants for controlling the event handling
instead of a mere boolean value.

The GDK_EVENT_PROPAGATE and GDK_EVENT_STOP constants map to FALSE and
TRUE respectively.
