Orderable TmplAtom

[Tristan Croll]

The following bug report has been submitted:
Platform:        Linux-3.10.0-1062.9.1.el7.x86_64-x86_64-with-centos-7.7.1908-Core
ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC)
Description
Minor API-related issue, but it would be good if `TmplAtom` had some form of `__lt__` method defined to make it orderable. I'm not sure if it particularly matters how (by name?), but orderability is required for some algorithms (e.g. `networkx.isomorphism.ISMAGS` for finding the maximal isomorphous subgraph between a residue and its template). In this case I can trivially work around it by switching the order of arguments since `Atom` *is* orderable, so there's absolutely no urgency here.

Hmm... I stand corrected. I *can't* work around it by changing the order 
of arguments - but I'm sure I can figure something out.

What defines TmplAtom?

TmplAtom now sorts on name. In the next daily build.
