Mod key-binds are sometimes empty on fresh install
Users running a fresh install of the 2.0.0 release reported that mod specific key-binds are sometimes empty and don't assume their default values. They had to be set manually from the settings menu, after which they were persisted accordingly.
I suspect this occurs when running vanilla Xonotic first and the Vore Tournament mod afterward; When the "data" settings are generated, the custom key cvars are likely configured by Xonotic and set to empty values... then when Vore Tournament first runs and generates the "data_voretournament" settings, it sees that they already exist in "data" and leaves them be. The obvious solution would seem forcefully setting them at game start, but then changes made by the player won't be persisted! As such finding a correct solution might be tricky.
