Shout-out to TAG's config that somehow had
`setcontrol2 "custom3" "KEY931926528"`, cuasing the game to crash only in
Splitscreen.

Actually actually match the old behavior and check existing levelflats in P_AddLevelFlatRuntime BRUH

Fix title screen broken when leaving during resynch

Also moved the debug down in case anyone uses that.

This reverts commit ea129f70.

In splitscreen stuff, player 2's "cam2_turnmultiplier" implementation
was wrong compared to player 1's "cam_turnmultiplier"
This commit makes player 2's multiplier work just like player 1's does
