Common JS polyfills

A collection of JS polyfills for modern APIs. Build them into your project as needed. They are broken into logical chunks to be included a la carte.

This is currently Alpha. The polyfills are currently untested. Make sure to test your code rather than assume in browsers that need polyfilling.

These are meant to support back to IE8. If you need support for IE7, some of these polyfills may not be helpful.
