Suppress new deprecation warnings when running the

test suite.

For urllib2, move the import of gopherlib into the
only function that uses it:  users (including the
test suite) certainly shouldn't see a deprecation
warning just because they import urllib2!  If they
actually use gopher_open(), fine, _then_ they should
see a deprecation warning.
