NPM/Bower and UMD support.

Browse source 
- Supports `require()` and `define()` style loading.
- Is available on Bower through Git tags. Not yet via NPM. (run `npm publish` inside the project to do so)
- README updated with hint of usability with module loaders

In the code:
- Implemented UMD method, using AMD in first instance.
- Error is thrown is the root KuteJS could not be found.

What is missing:
- Sub-modules should export their factory rather than doing this on their own.

* properly replaces `top`, `centered` or any other background position with proper value to be able to tween
* for most supported properties it reads the current element computed style property value as initial value (via `currentStyle || getComputedStyle`)
* because it can read properties values from previous tween animations, KUTE.js can do some awesome chaining with it's `.to()` method
* allows you to add many callbacks: `start`, `update`, `complete`, `pause`, `stop`, and they can be set as tween options
