Made paths more consistent between client and server and friendly to RequireJS.

Spike,

This is next iteration of making Rendr play nice with RequireJS.

I made grunt script to fetch-n-wrap all the modules from rendr folder needed in the browser,
despite verbose config (and supposedly fixed bug) it works fine.

So it's first subset of changes to make Rendr truly client-side citizen.

Let me know what you think and if you ok with this direction.

Thank you.
