Feature/runascgi

This PR adds a wrapper script and documentation on how to run this application as a CGI under apache. The [preferred method](https://docs.djangoproject.com/en/1.3/howto/deployment/modwsgi/) of running django is via mod_wsgi, however in our shared hosting environment that is not currenlty an option, so this is a workaround for that. The script that bootstraps django in a CGI environment is a [modified version of django.cgi](https://code.djangoproject.com/attachment/ticket/2407/django.cgi).

This is now running at harmonylab.fas in the shared hosting environment.

@jazahn Can you review this?
