Prep for first release

Made some metadata changes to the project to prep for first release. @pushred At one point, you had made a comment about adding Sparkart info in the package.json, but I'm not sure what field(s) to add that in.

Since this is my first time releasing, I'm figuring out the process as I go;

Bower: http://bower.io/docs/creating-packages/#register

npm: https://gist.github.com/coolaj86/1318304

GitHub: https://help.github.com/articles/creating-releases/
Yeah, this was automatically generated by `bower init`, so there's a lot of stuff in there that probably doesn't apply. The only ones I'm aware of being needed are `build/*`, `node_modules`, and `test/mocha/tests.js`, but I figure it can't hurt to have the rest in there. Could prevent any of those things ever getting accidentally committed in the future.
