Reworking

Hi,

I'll send this pull request just as a headsup if you want to check out this rework and give comments if you see problems with it. 

Basically what has been done:
* BackBone dependency removed
* Project structure cleaned up to resemble the official Yeoman generators
* Scaffolding the `index.html`
* Scaffolding for CraftyJS scenes
* Scaffolding for CraftyJS components
* updated package dependencies for grunting to the latest, resembling the official Yeoman generators
* cleaning all files from trailing whitespaces
* etc...

Let me know if you'll think this has potential to get merged in.

Thanks!
