API Fetch Activity format=...

Browse Source 
.. when retreiving an activity using the API
   you can now specify the format you want the
   data to be returned in.

   it can be one of;
   tcx - garmin training centre xml
   pwx - training peaks xml
   json - goldencheetah json
   csv - all available data (not powertap csv)

.. along the way the file writers for the respective
   formats now accept a NULL context to work standalone.
   this may be useful as a file conversion tool.
