Made the README better

I've re-written the README with some new features.

__New Title__
![pull-1-1](https://f.cloud.github.com/assets/5531132/2034673/ee056492-892e-11e3-9b6c-f448c7980d9e.PNG)

I've added a logo and a smaller tagline.

__Better Browser Support Box__
![pull-1-2](https://f.cloud.github.com/assets/5531132/2034682/100742c2-892f-11e3-972d-b0bbee806e6e.PNG)
The browser support box now has links to the browser's homepage.

__ Demo Link __
![pull-1-3](https://f.cloud.github.com/assets/5531132/2034689/204dd132-892f-11e3-927e-092668ea2ee9.PNG)
'nuff said.

__Dependencies__ _(requisites)_
![pull-1-4](https://f.cloud.github.com/assets/5531132/2034699/441bf31e-892f-11e3-9d6f-17085df97649.PNG)_

__Usage__
![pull-1-5](https://f.cloud.github.com/assets/5531132/2034715/78bea0c6-892f-11e3-8bd6-d074783c3b09.PNG)
I've fixed the usage box. It now has syntax highlighting and uses regular markdown expressions rather than HTML tags,

__And, lots more.__
