Added: favicon, fixed paths.

**Summary:**
- Added: favicon (it's much easier to find right tab now) ![screen shot 2014-05-15 at 10 26 20](https://cloud.githubusercontent.com/assets/524216/2981308/ac393a8e-dc03-11e3-8372-65584687a7c6.png)
- Fixed: paths

**Note:**
I'm not a designer, actual icon could be improved by one.
