Back/Forward support for url fragments

Added support for anchor (url fragments). this involves 
mainly implementing IPersistHistory. The rest of the stuff
is a song and dance to get called in IPersistHistory in the
first place and then behave correctly when we do.



BUG=23981
TEst=unit tests added and back forward with '#' URLs, sub frames etc.
