Merge pull request 'Adds Oekaki to roulette.' (#40) from enableOekaki into config

Adds Oekaki to roulette.

These are the settings that needs to change to enable oekaki. It uses somewhat of a hack due to our other settings. It works well as far as I can see.

There might be some work needed to have this work on the site.
Namely, git submodule init; git submodule update and possibly run npm install -ci; grunt --force too in the wpaint submodule.
