Closes #142
Why
Currently, Refresh does not validate the ScoreType (aka the game mode or player count) when submitting scores. This isn't too big of a deal since the game only checks certain score types, but it's quite trivial to protect against so we might as well.
How
To do this, we simply validate whether the score type is either between 1-4 players in co-op mode or 7 for versus mode.
Remarks
We could do some further validation, checking the level's version and type but I think this is enough to stop most abuse.
