automated server update upon commits to master

[antont]

currently the update procedure is manual: ssh to Ludo's filab VM instance and say:

lc-test2:/var/www/fidemo# git pull; git merge origin/master

the server uses the servertweaks branch where the client is configured to connect to that server. (originally it required also tweaking asset ref urls as a hack but not anymore).

it would be possible to put a daemon there to listen to commit notifications from github and do that automatically.

note that we setup github pages so people can push to gh-pages branch to update http://playsign.github.io/fidemo/

the filab server with tundra running too is still updated manually.
