Title: Added selection array to the model.

In this pr a list of ModelEntities is added to the model in order to keep track of the selected elements. Implemented as we talked with @anserran prior to the meeting, today.
Keep in mind that this is necessary in order to be able to add functionality to the Tween Edition Widget.
