Coffeescript with browser compiler

I will put this there and let you decide what you want to do with it :)

I had to do some changes:
- removed ng-app, since the app script loading id delayed we need to bootstrap manually and the end of the script when ready
- fixed an issue where string containing numbers and numbers were compared (world ids), coffeescript "==" is more strict than js ("13" == 13 returns true in js !!!)


PS: the conversion commit did not changes anything regarding the code itself, I just did the conversion, everything works like before as far as I can tell (except for the comparaison bug I fixed after of course)
