"rename" error changing model number in some cases

[Elaine Meng]

Reclassify as desired.

If I have two models open, #1 and #2, entering this command works fine

rename #1 id #2

... result is #2 and #2.1 as you told me was the intended behavior, but the Log strips the second "#" even though the Command History shows it. However, if I instead use command

rename #2 id #1

... there is an error and the model number isn't changed (Log has the second "#" stripped again, but that seems orthogonal to the error... or was I not supposed to include it in the command??)

Log shows:
rename #2 id 1

There are two bugs here. The first is the logged command drops the "#" character. Greg issue, but easy to fix so I fixed it. Second bug is in Model Panel. Reassigning to Eric to handle that.

Fixed. Needed to always rebuild model panel if model IDs change, and get the ID-change trigger to fire when models reparented.
