Not a pancaea for EVERYTHING, just a bunch of good stuff.
* Some issues with spectators not == true because the assignment wasn't casted.
* Netgame status (or rather its inverse) is recorded in netreplays now, to allow for power levels controlling spawn position.
* Fixed tally screen for replays to not scream infinitely at you.
* P_IsLocalPlayer now uses display players in replays.
* A bunch of good testing prints that helped me find these problems, commented out for now just in case we need them again soonish.
