Title: Add a scene navigator. Fixes #2.

Now that undo is on a different development track, another go on scene navigator patch.

* We use a simple timer o collate screen updates, which is currently set at 500ms. So if you make a change within that time, the timer goes back to 0.

* Certain actions (line count change, mouse actions) cause immediate updates.

* Select scene is still included.

@oskusalerma: please try this when you get a chance.
