WIP on a deployment script

Run the following command from within your local git clone:

    fab deploy

This should take care of everything, provided you've made the initial
install configuration on the target server (see the readme for info).

Our app uses virtualenvwrapper and we use it on the production server,
too.
Restart the uWSGI server by touching app.wsgi
Remove an unneeded symlink

This folder is created automatically during deployment.
Update the production install instructions

We'll be using sample files for the configurations and thus we can't
and probably shouldn't just symlink to them.
All server configs are just example opnes
Make the servers' example configs more generic
Offer to restart the uWSGI server by touching a file
