Beginning of GAE port

Notes:
* Still unclear how we should handle secret information such as
  keys and tokens.
* app.wsgi better be renamed to app.py
* In GAE, we would have to use memcached, so Redis must be changed.
* For https, certificates will have to be handled differently :/

So we still can't just migrate to GAE, but this is a start, so I will
commit, and keep it.
