Improve session store and restore

This is the review from Simon Schampijer of commit
14102bcd65f015dcbf12d1406df8ef7ffb64d13d .

* the sessionstore code is moved into Browser, we do have
  set_history_index/get_history_index already there, the TabbedView
  does use that path for their requests about the history

* Rename a few bits s/session/history and the return value from
  self.get_back_forward_list() Use back_forward_list as variable

* Fold _get_history and _set_history into their appropriate 'mother'
  methods

* Make set_history_index a bit cleaner, the API provided by webkitgtk
  does not seem to cleanly allow our usage like:
  get_current_item_index and go_to_back_forward_item(index) also the
  API does seem to miss a back_forward_list.get_length() (see the code
  we have to do in _items_history_as_list) there only exist a
  back_forward_list.get_back_length() and
  back_forward_list.get_forward_length().
