Fixes pawns sometimes not properly going to sleep when changing maps in async multiplayer.

Implementation-wise this mod just checks if a pawn's canSleepTick is more than 1,000 ticks above the game's current tick (Find.TickManager.TicksGame), which can only happen (in vanilla at least) when a pawn has changed maps while playing in an async multiplayer environment. It's a quick-and-dirty fix, and doesn't account for any mods that may offset that value by more than 1,000 (I don't know of any, but you never know).
