Added noWrap property.
- to be used when you want to render directly into a region or view and not wrap the view with a `tagName` property.
Added `noWrap` docs.
Remove callback from old events signature in `region:find`
- send the reponse back directly
Make sure a region was found when assigning `this.el`.
