LibWeb: Implement navigation.{traverseTo, back, forward}

Browse source 
The proper abstract operations on Navigable and TraversableNavigable are
not quite ready to call from Navigation. With this commit all of the
user-facing APIs of Navigation are in place, and the stage should be set
to implement the parts of the navigation and traversal AOs that need to
interact with the Navigation object.
