X-Editable for Yii 1.2.0

Rationale: I need working editable widgets and had many issues getting yii-bootstrap-editable to work. It makes sense to add this the successor of yii-bootstrap-editable to phundament/app regardless of the fact that gtc and p3media still haven't been upgraded. Hopefully they will follow suit soon...

Have verified that p3media editable still works after applying this patch on a clean phundament installation.
