[Rails-devel] Save now also possible at game start

[Erik V. <eri...@xs...>]

Games can now also be saved at game start, as appears to be useful for PBEM
play.
This fixes the first half of bug report #2923608.

The second half is unrelated and has been copied to a new bug report
#2924585.
This is about modal dialogs that must be reponded to by a different player
than the one who did the last move.
For PBEM play it would be useful if a Save would be possible in between.
However, that requires the invention of a non-modal way to get prompts
answered, which doesn't yet exist in Rails.
(This problem therefore IS closely related to the map visibility problem
during the CGR formation, as discussed a few days ago).
