Add in some lovely ignores

Added some ignores to your bower.json file.

Why?

* .jshintrc: in case you want to do some linting in the future
* index.html: This can be a security concern for some sites (like the one I am making now) 
* *.json, so I dont get the bower.json information on a live site
* README.md, again, I dont need this in my app. 

Thanks!
