Tentative support for friend and game syncing

With thise code each time a user logs in a sidekiq job will get
created to sync their games and friends lists. To trigger the job
we'll need to start sidekiq.

These jobs are run within the "sync" queue. For now we can run sidekiq
on heroku using
'heroku run sidekiq -q sync'
Setting sync worker to perform inline for now
