Refactored setup scripts to use generic functions (which can be used to set up different environments). Added a first pass at a Pi deployment.

Likely gotcha: the nginx config needs to know where the static files are. That'll be different on the Pi. Need to think about parameterization.
Removed database file from repository, added empty fixture for development data.
Removed ENVIRONMENT (not needed since emoncms is gone) and updated README.
