js and css should be concatenated, minified, and served from a CDN (#866)

I'd like to try this with simplates at /assets/%version/gittip.css and /assets/%version/gittip.min.js that perform the concatenation and minification on the fly. @pjz had code for this in the Aspen repo somewhere.

In addition to concatenating and minimizing CSS on the fly, we should scss compile the CSS on the fly as well. (I assume the compilation will only be redone when one of the relevant source files changes.)

CSS done in #1245. JS done in #1302.

Was the intention of this ticket to combine all css and js? Because in the current situation that is not the case (we have chosen.css, reset.css and gittip.css on each page - from what I was able to find). Shall we reopen this one or create a new one? Minimizing the number of http requests is #1 optimization.
