Object frame progress

 From:  Michael Gibson
I've been making some pretty good progress on the first v2 feature, which is a frame type widget that shows around the outside of the selected objects. The idea is to make it possible to do quick scaling or rotation edits without having to start a command.

If you drag a grip towards the right, it will do a 1D horizontal scale:

If you drag a grip vertically, it will do a 1D vertical scale:

If you drag anywhere else that is not along those tracking lines, it will do a 3D scale.

My original plan was to make this frame show up only on 2D planar objects to start with.

I've kind of switched that around - now it looks like I will put it around all objects, but the frame only shows up in the ortho (Top/Front/Right) views.
