[Cuis-dev] Renaming several fundamental Morph classes

In DrGeo, geometric item views are direct subclasses of Morph, because 
you are not expected to drag these morphs around. The view is only 
positioned according to its math model. So this is an additional show 
case for a Morph without location attribute.

User may understand Rectangle when she will read RectMorph, but it can 
be many shapes in a rectangle extent (ellipse, disc, star, right 
triangle, diamond). BoxMorph and BorderedBoxMorph will reduce this 
confusion.
In the other hand, most subclasses of RectMorph are expected to be 
rectangular shape and Juan want it to be clear.
An EllipseMorph will be a subclass of RectMorph/BorderRectMorph, this 
look odd, but understandable though.
So likely *RectMorph* and *BorderedRectMorph* are very good compromise.

Regarding LocatedMorph and MoveableMorph, I found the latter inelegant 
and the former not really better. A more simple *MobileMorph* is so 
easier to pronounce, meaningful and elegant.

For the better to all of you.
