HTML and CSS files are not minified on deploy.

This adds CSS/HTML compression (and comment removal) to the compress
build task (used in `jake deploy`).

This adds two new (local) NPM modules:

- http://npmjs.org/package/cssmin
- http://npmjs.org/package/html-minifier

This also address this GitHub Issue:
