Added Post Round Timer

30: Faster "FreezetagThink"
- Speed of think raised, for smoother gameplay/clock/checking, may be
lowered again

87: GameRules:SetTimeOfDay( 0.25 )
- Used to insure the start of every round is daytime.

94: Variable changes
- Basically making sure the round counts up, and that preptime is ready
for Roundstate prep, and that Posttime is ready next Postgame.
