Allow configure to deal with Python 3.0. Changes were:

print foo --> print(foo)
string.join(...) --> ' '.join(...)

These changes are backward compatible.

The actual plpython module appears to need significant updates to support
Python 3.0, though.  This change just relieves interested developers from
having to deal with Autoconf.
