Specialized undos + undo move

[olibclarke@…]

The following bug report has been submitted:
Platform:        Darwin-18.6.0-x86_64-i386-64bit
ChimeraX Version: 0.9 (2019-06-05)
Description
Hi,

Given that the undo/redo actions seem to be separated into a limited set of commands, would it be possible to allow independent specification of the "substack" of undo/redo actions pertaining to that particular command? E.g. "undo color", "undo select", etc? 

This would allow undoing a color change, even if the user has (for example) changed the selection or style in the meantime.

Undo/redo move was also really useful in Chimera - would be great if they came back at some point too.

Cheers
Oli
