message:
  Implement a 'bzr push' command, with saved locations; update diff to return 1.
  
      * 'bzr diff' now returns 1 when there are changes in the working 
        tree.
  
      * 'bzr push' now exists and can push changes to a remote location. 
        This uses the transport infrastructure, and can store the remote
        location in the ~/.bazaar/branches.conf configuration file.
  
      * WorkingTree.pull has been split across Branch and WorkingTree,
        to allow Branch only pulls.
  
      * commands.display_command now returns the result of the decorated 
        function.
  
      * LocationConfig now has a set_user_option(key, value) call to save
        a setting in its matching location section (a new one is created
        if needed).
  
      * Branch has two new methods, get_push_location and set_push_location
        to respectively, get and set the push location.
