Further desync investigations

[freddyhayward]

I made a thread earlier about a desync (then-crash, though the crash itself was fixed: https://forum.simutrans.com/index.php/topic,19892.0.html) occurring when a schedule was being edited is interrupted by a force-sync. I have since discovered that this occurs in many more cases, including:
- renaming a stop
- renaming a city (which shouldn't be allowed regardless)
- renaming a line
- renaming a convoy
- renaming an industry/factory
What all of these have in common is that they are all tool actions created when a window closes. In this case, the windows are closed as a result of the force-sync.
However, there are some actions that fit this description that do not cause desyncs, including:
- renaming a player
- creating or renaming a marker.
