Lots of changes/fixes/things I would like to see

This is really just a template on things that I want to see plunder do.

I fixed the r.js build task to wrap your output in a UMD wrapper that attempts AMD, then CommonJS and falls back to a global namespace if neither are available.

I also cleaned up things that weren't being used in the Gruntfile and package.json.

Instead of `compiledjs` directory, I built the coffeescript AMD files to `dist/amd` so Frozen would be able to pull in individual modules.

The AMD modules weren't using local filepaths, which would cause problems when trying to specify Plunder in an AMD packages array.

I also made some changes to gh-pages to work with these changes and will be submitting that as a PR.
