Patch notes

 * Fix the Theater issues that are preventing some players from viewing some cutscenes
 * Some backend work to prepare the game for disconnecting from HaloWars.com. This was a fairly significant amount of work, as we wanted to be sure that multiplayer for the game still functioned properly without HaloWars.com and other backend support.
