SOCD detection

[b1az3]

1. Automatic warning if the server detects SOCD (can be enabled or disabled by the admin by modifying k_allow_socd_warning)
2. Command to check f_movement, summarizing for each player if the server detected anything. (ex: cmd check f_movement)
3. End-of-game stats to show if SOCD was in use.

oof... ought to be deleted instead, but separate PR, Visual Studio can import cmake projects nowadays.

maybe just skip these and delete tools/vs in a separate PR

And get rid of the useless merge commit. Just reset to origin/master and cherrypick your commit to that and force push to your branch.

My concern is that this, as it's currently implemented, is a bit opinionated and invasive and has a shaming/discouraging effect on the players.

I think instead of notifying the server that a player is doing something potentially wrong, we can report the strafing numbers in the end-game player stats in a more neutral manner. This will still allow tournament admins to make their own determinations, without you having to decide for everyone what the tolerable thresholds are.
