New concept for style.css

Yes. Its a radical idea:

For the sake of best practices and taking advantage of the of less, I propose to...

* move everything but the meta information in `style.css` to a new location of `library/less/wp.less`
* call `wp.less` in the `bootstrap.less`
* stop calling `style.css` in `functions.php`
* I hope I'm not missing anything else relevant

... all into the 3.0-wip branch.

This would just be like the [roots](https://github.com/retlehs/roots) or [bones](https://github.com/eddiemachado/bones) theme. It kinda goes against the idea of a clone of bootstrap in a wordpress theme. I have used this technique in the past without difficulty. Its just another thing to think about. This could be quite controversial, what do you guys think? There is really no rush on this, so just keep it in the back of your mind.
