can_go methods now work, WebKit was missing the implementations for those

2007-07-30  Diego Escalante Urrelo  <diegoe@gnome.org>

	* embed/webkit/webkit-embed.cpp:

	can_go methods now work, WebKit was missing the implementations for
	those functions, it's fixed now so we can use can_go methods.
	Note that they are useless without the ge_location signal being
	emitted (dummy code included, commented).

	Part of Bug #461652.
