Remove dependencies.

First off, great work.

In reading, noted that zoom.js could at most target IE 9 (given use of transform). With that thought in mind, would you be against making the library independent?

The main risk is entirely dropping support for < IE 10. However, the upshot is that zoom.js should work on its own for most people.

Notes:

• Element.classList is unsupported in IE9
• Removed dependency on $.support.transition.end, which could be an issue if emulateTransitionEnd is actually required for target browsers (which I imagine was intended for IE9?)

this is interesting, but i think going the wrong direction… i'd rather see better browser support then worse.

@kruppel: shameless plug, but my fork is perhaps something like what you're looking for: https://github.com/spinningarrow/zoom-vanilla.js? It's this zoom library, without any jQuery dependency.

Btw, really nice work @fat!
