iBraining goes mobile

It's a big day, It's nearly Christmas ! iBraining is now (nearly) fully playable on smartdevices (phones, tablets, small screens, ...).

It's not a big rewrite from scratch (like I planned), not a SPA app, not riotjs/angular* powered! I've just hacked the html/css to be a responsive app, to adapt itself to smallest screens. It should do the job.

Desktop version continues to work ;-), just small changes in the front.

Hope everything will continue to work for everybody.

PS: I will continue to work on it in the future days (mainly : better rendering).
