Add enyo latest and 2.2.0 to libs

Hello,

[Enyo](http://enyojs.com/) is a cross-platform JS framework designed for mobile devices, and is part of the [Open webOS architecture](http://www.openwebosproject.org/docs/architecture).

It is used by companies such as [OpenBravo](http://blog.enyojs.com/post/33181474956/openbravo-selects-enyo) and [xTuple](http://www.xtuple.org/a-shorter-letter-enyo) for their mobile applications.

We're also using it at [hinnoya](http://www.hinnoya.fr/) for some of our mobile applications. Jsbin being a great open source alternative to jsfiddle, so I thought it could be interesting for it to support the Enyo libraries as well.

Kind regards.
