Lib-Index:
- Adjusted jQuery Version Description
- Updated Handlebars (1.3.0 -> 2.0.0)
- Updated Underscore (1.6.0 -> 1.7.0)
- Updated KnockoutJS (3.1.0 -> 3.2.0)
- Updated ZeptoJS (1.0.0 -> 1.1.4)
- Updated Phaser (2.0.7 -> 2.1.1)
- Deleted FastJS (discontinued?)
- Added EmberJS as new lib
- Moved Underscore above Backbone.js

I also improved the path display in librarylist.html. It is now italic.
