Body.Body now has a TabChain. It now also stores the most recent mousedown event.
- Added support for a constructor to appear with namespace and name in webkit-based debuggers. Eg for a namespace "Foo": var Bar=Tools.View('Foo.Bar, {..})
- Added a new selection model mutating its member models.
  All controls, as well as the Menu now uses these selection models.
- Added new bool option to Tools.Selection "dragselect", set it to false to disable drag selecting of items.
- Traits.Model now support getters using the syntax "get_foo"
- New property for Traits.Model "setorder" controls the setting-order when assigning multiple attributes at once.
- Traits.Model.toJSON now includes attributes without a corresponding trait as well.
- bugfix: Tools.View.hotkeys were not applied
- Removed the last remnants of monkeypatching backbone's builtins (Backbone.Model, Backbone.View etc).
ErrorMessages is no longer a default mixin for SimpleForm and CustomForm.
Named some Form classes.
Some sass updates. Revert the renaming of .tiki-disabled. It needs it prefix since it can be used "globally" on a parent dom-element, disabling all contained controls.
