Make Sponsor use the new DynaForm module
Currently only a slight reduction in code, but hopefully some

Added a DynaForm module
This allows GAE forms to be defined 'semi' dymamically, rather than
by having to explicitly create the new class.

Added a cleaning module
This module is the start of a (hopefully more generic) set of
cleaning functions that can be used in the GAE forms.
