ticket 1705 - internationalize help topics

* Wrap each topic description in _()

* Replace the use of if 'topic' in dir(module) with the more
  Pythonic and efficient getattr(module, 'topic', None)

* Make sure to invoke unicode on the value returned from _()
  otherwise you'll get a GettextFactory instance, not a string

* Clean up trailing whitespace errors
