Make combine command create shorter new chain ids

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-12.3-arm64-arm-64bit
ChimeraX Version: 1.4.dev202203161710 (2022-03-16 17:10:18 UTC)
Description
The combine command renames chains in a very strange way, for instance making some 7 characters chain IDs such as 0000008 when combining 216 copies of 1a0m (3 by 3 by 3 unit cells).

It would be nicer if it used some more obvious predictable new chain names that were only two characters of two characters suffice.
