Fix build errors

Grunt was failing due to some of the refactoring work that's been going on in pelement, and I noticed that since we weren't using QUnit for tests anymore the `grunt test` command wasn't working either. This should fix both errors.

@evhan55, based on our conversation today I added a commit to include the updated `lib/` and `docs/` folders that were regenerated after running Grunt. Let me know if there's anything I should be doing differently here.

I would like to rebase #223 on top of this if this PR gets merged, since it will make updating the getNormalizedColor tests easier.
