[BUGFIX beta] Fixes issue - class given as unconditional binding to view not applied.
[DOC release] Update binding.js

* Changes one of the code examples to use a more correct representation of what
  the `.from` property is actually expecting.
* Adds a couple examples to help clarify that bindings may be set between
  objects using this method, and not just inside the object passed to `connect`.
[BUGFIX beta] Use already declared `trim` instead of `jQuery.trim`

Use ActionManager to register in-template actions
Remove deprecated action lookup as methods on controller.

The older lookup in the root of the controller has been deprecated
since late-2013, and is a frequent cause of annoyance for newcomers.
This PR removes the deprecated lookup completely.

This has been discussed with the full core team.
