- Add a simple UIFactory 

  The idea of this is to let a client of bzrlib set some 
  policy about how output is displayed.

  In this revision all that's done is that progress bars
  are constructed by a policy established by the application
  rather than being randomly constructed in the library 
  or passed down the calls.  This avoids progress bars
  popping up while running the test suite and cleans up
  some code.
