Subject: [PATCH] Made the various is_* operations return booleans.  This was
 discussed with Cawlishaw by mail, and he basically confirmed that to these
 is_* operations, there's no need to return Decimal(0) and Decimal(1) if the
 language supports the False and True booleans.

Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).

Thanks Mark Dickinson
