Bug Description

A save game can only be written from the in-game menu, so producing one means playing to the point of interest and clicking through Save. #3001 adds -loadsave for the other half of a round trip, but with no way to write a save unattended there is still no way to run save and load end to end from the command line, which is what checking an xfer change needs.

Reproduction Steps

1. Start a map from the command line with -file.
2. Try to produce a save at a chosen point without using the in-game menu.
3. There is no command line option that does this.

Additional Context

-file already starts a map from the command line in debug builds, and #3001 adds -loadsave. An option to write a save at a chosen logic frame would complete the pair.
