* Implements the new query-continue procedure in the MW API - The current querycontinue
  option in APIRequest.query() is deprecated and will be removed in a future release.
  A FutureWarning is issued for invocations of query() where the 'action' API parameter
  == 'query' and querycontinue is True (the default setting). To silence the warning, set
  querycontinue to False if unneeded or use the new queryGen() generator function.
  queryGen does not attempt to stitch together the results into a single object, so it
  requires slightly more effort to use, but the results should be more reliable.

* wikiFile.File.getHistory is renamed getFileHistory, so as not to conflict with the
  same-named function in Page. getHistory() will still work as previously for now, but
  issues a FutureWarning
