Allow PL/Python functions to return void, per gripe from James Robinson

Browse Source 
(I didn't use his patch, however). A void-returning PL/Python function
must return None (from Python), which is translated into a void datum
(and *not* NULL) for Postgres. I also added some regression tests for
this functionality.
