Concatenate frontend resources

[markjaquith]

This comes as a suggestion from Google, who wants to help publishing platforms deliver content faster.

Many WordPress sites suffer from too many separate CSS files and JS files. They could reduce HTTP requests and improve performance by concatenating these together. If we do this in core, we can include plugin resources as well as theme resources.

There's a dupe of this somewhere. It relates to extending the WP scripts and styles classes, or depends, to make it core.

Btw, it's not too hard todo with a plugin.
