Set up machine/VM to run Tor Weather on

We just finished the GSoC project to re-write Tor Weather and we would like to deploy the result now with weather.torproject.org as the respective domain.

@sarthikg: could you make a list of things we'd need to have available on a new machine/in a new VM to have Tor Weather running properly? And maybe some spec that VM/machine? Thanks!
