Mouse modes goes bananas

[Tristan Croll]

The following bug report has been submitted:
Platform:        Windows-10-10.0.22621
ChimeraX Version: 1.7rc202311140124 (2023-11-14 01:24:52 UTC)
Description
Merged a ligand generated from SMILES (which is loaded with a chain ID of "?") into ISOLDE's working model. Used the "bond rotation" mouse mode on it, leading to the error "Must specify exactly 4 atoms for 'torsion' command; you specified 8" being spammed to the log (it does actually still rotate the bond, though). That's not the fun part, though: it's left the session completely borked, with *every* mouse button (with or without modifier keys) all going to rotation of the bond I originally clicked, even though that mouse mode is no longer assigned to anything (see below - note that the modes with the generic "mode name" are Clipper modes... I'll see about fixing that):

for b in session.ui.mouse_modes.bindings:
    print(f'{b.modifiers}-{b.button}: {b.mode.name}')

New template added to forcefield as USER_TRZ. This ligand should now work in
all remaining simulations for this session. To use in future sessions, load
the ffXML file with ISOLDE's Load Residue MD Definition(s) button.

Saving the session to .cxs and then reloading it (in the same ChimeraX
instance) did fix it, though.

Minimal reproduction test case:

{{{
open C1CN(CCN1CCCN2C(=O)N3C=CC=CC3=N2)C4=CC(=CC=C4)Cl fromDatabase smiles
open C1CN(CCN1CCCN2C(=O)N3C=CC=CC3=N2)C4=CC(=CC=C4)Cl fromDatabase smiles
setattr #2 residue chain_id A
view matrix models #2,1,0,0,-0.96656,0,1,0,-3.8786,0,0,1,-0.67812
combine #1,2
close #1,2
ui mousemode right "bond rotation"
}}}

... then right-click and drag on any bond in the "?" chain.

Also, combining structures with blank IDs with structures with non-blank IDs is problematic, because the only atom spec chain ID that matches a blank chain ID is "/?", which actually matches any chain ID. This probably the cause of the "Must specify exactly 4 atoms for 'torsion' command; you specified 8" message, the /? matching both ligands.

I have changed the "combine" command in the daily build to remap any blank IDs in addition to remapping conflicting IDs.

Fixed the stuck mouse mode in ChimeraX 1.8 daily builds, not in 1.7.

The bond rotation mouse mode gave an error when the mouse button was released and that caused the mouse mode code to fail to exit that mode. I now catch mouse up errors and make sure the mouse is not left in that mode.
