JSHint and JSCS mwEmbed codebase

[hartman]

There is a statement in the readme that the code follows mediawiki code conventions, but that is far from true :)

I have started a jscleanup branch on hartman/mwEmbed with that exact goal in mind. I have so far taken care of initial setup and making TimedText pass this setup. The final goal for me is to improve the next attempt of bringing the MW and Kaltura versions closer together again and easier to maintain.

Thanks @hartman
I'm adding @OrenMe (one of our developers) who will help to include the jshint to our build.
