Google have now allowed documents to be downloaded via their API
(http://googledataapis.blogspot.com/2009/02/start-downloads.html) so
the google docs repo plugin could be finished.
At the moment i've set the export format hardcoded, hopefully we can allow the
repo api let the user choose later...
That allows us to have a few sentences explanation of each question type, and is also easier to fit into a tight layout.
This commit should also fix MDL-18214 Layout screwed in Safari with long category names.
