retain object selections after transferring morphs

[Luke Graybill]

It would be handy if the morph transfer tools could restore the initially active object when it is finished operating. I don’t know how many times I’ve used “Transfer JCMs”, then pushed the “Transfer Other Morphs” button without realizing that the main body mesh is no longer active.

(Note that recent commits seem to deselect all meshes, which is slightly different from how it worked for months before - where one of the selected meshes would become the active. Regardless of this newer behavior, my suggestion stands.)

Steps to reproduce

Select geograft, then select body mesh as active object:

Transfer JCMs:

Transfer process completed, but different mesh is now active entire selection is lost:

Ugh, formatting issue descriptions on Bitbucket is a pain in the ass without a preview feature, but I think I got it readable now

Implemented in last commit. In fact, all buttons will have this property. Hope that that does not break something.

The change does in fact retain the active object, that’s great! However, the selected (but not active) objects are still deselected.

Also, importing a figure when no object is currently selected in the scene produces an exception (although the import seems to complete):

The issues should be fixed now.

Seems to be working great now, as of build 1010.
