[not ready] Add uncss and uglify to the dev environment

Uglify is a modern JS minifier (YUI is long dead) and clean-css does massive optimizations to CSS beyond minification, like merging likewise selectors and more.

Notes
*  I'm not sure I have these puppet manifests correct
*  I had to upgrade NodeJS to get a reasonable clean-css and uglify version.

So...this is minimally waiting on (1) IT to upgrade Node and (2) someone to tell me if I've done the puppet stuff right.
Not going to block on this, obviously, but it looks like EditorConfig missed this. It should be adding newlines to all files.
