Destroy the GtkPlug when the plugin is destroyed

Previously the GtkPlug was being implicitly destroyed when the
EvbpViewer object was destroyed. This worked fine under firefox where
the plugin code jumped through hoops to make sure the GtkPlug was
disconnected before destroying its GtkSocket, but other browsers may not
perform this trick for us.
