Don't spam the file history when opening a cluster in the similar structures tool

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-15.4.1-arm64-arm-64bit
ChimeraX Version: 1.11.dev202505062043 (2025-05-06 20:43:22 UTC)
Description
Make similar structures not add entries to file history when the Open button is used to open more than one structure.  It is too easy to add 50 unwanted structures to file history.
