Subject: Use strings not unicode in password module
X-Git-Tag: 0.0.1~282
X-Git-Url: https://mudpy.org/gitweb?p=mudpy.git;a=commitdiff_plain;h=26963f7304e824d3781da7de4ef677d981412766

Use strings not unicode in password module

* lib/mudpy/password.py: Python 3000 treats strings as unicode by default,
so we should too.
