Add new edit tool icon, shortcut, and basic modes.

* It allows you to select multiple objects to edit instead of just one.
 * It highlights the object lines and the points in red.
 * It stays in the mode and allows you to run other modifiers.
 * A very hackish hook into the move modifier is added as a proof of concept.
