Title: Inspector migration  - PART1

Missing pieces (will be addressed in PART2):
* Sidebar (rule/computed/layout views) and Tilt have been ignored.
* Only a couple of tests have been updated.

What changed:
* `InspectorUI` doesn't exist anymore
* A `Selection` object (wrapper around a DOM node) is shared between the different components of the inspector. This object fires events.
* The concept of "locking" is now only part of the highlighter.
* It's possible to select nothing.
* uses toolbox API
* more things
