configure uses inconsistent descriptions of virtualenv options.

ac_user_opts='
enable_option_checking
with_python3
with_virtualenv

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-python3          Set up to use Python 3 by default.
  --without-virtualenv    install to a Python virtualenv

right now the setuptools variable packages only includes 'mediagoblin'. This causes './setup.py install' or './setup.py build' to only pull in things that are in the package '^{mediagoblin$', and nothing else, like mediagoblin.*}

Only .po files should be there. .mo files can be generated on various stages, including package building or setup.py installation.
