Deploy script

[richvdh]

Creates a new deploy script, hopefully suitable for deploying riot.im/app.

Currently the deploy process is:

(cd packages && wget https://github.com/vector-im/riot-web/releases/download/v$VERSION/vector-v$VERSION.tar.gz)
(cd deploys && tar xvf ../packages/vector-$VERSION.tar.gz)
ln -s `readlink -f config.json` deploys/vector-$VERSION/
ln -snf deploys/vector-v$VERSION staging # (or beta)

(where the middle of that is deploy.sh).

This will become:

./deploy.py https://github.com/vector-im/riot-web/releases/download/v$VERSION/vector-v$VERSION.tar.gz
ln -snf deploys/vector-v$VERSION staging # (or beta)

Looks good, although we may want to verify the gpg signature on the downloaded tarball, which would just be a case of downloading the .asc file and running it through gpg.

PTAL. We'll need to download the gpg key to the deploy server, something like:

gpg --keyserver pgp.mit.edu --recv-keys E019645248E8F4A1
