Django-development-fabfile

- Turned environemnt specific settings into function and added lambda function
to fabfile_settings.py.sample
- This finally allows to deploy to different servers (we had never tried that
before and the old way didn't work, because many of the settings need to
know the LOGIN_USER and that user will be different on different machines
on Webfaction)

- Added run_makemessages and run_compilemessages commands
- Added MAKEMESSAGES_ON_DEPLOYMENT and COMPILEMESSAGES_ON_DEPLOYMENT settings,
please update your fabfile_settings.py
- run_deploy_website now executes makemessages and compilemessages, if the
settings are set to True

- No longer restarting apache on run_deploy_website, touching wsgi file instead

- Added selenium kwarg to fab test task to isolate selenium tests if you want

- Added run_export_media task
- Added run_download_media task
- Added import_media task
- Added new setting MEDIA_DUMP_FILENAME to fabfile_settings.py.sample
- Fixed path of SERVER_MEDIA_BACKUP_DIR in fabfile_settings.py.sample
- Please update your fabfile_settings.py with those two fixes!

- Added local reset_passwords tasks.
