Missions spawned through events with the LW2 Pack installed should now have mission rewards for doing them, when applicable.

Soldiers who are infiltrating can no longer be used by events.

Fixed logic error with how units are selected

Actually fixed XcomEngine.ini's issues with LW2 1.1.

Updated XComEngine.ini to not inadvertently break Long War 2 1.1.

Added additional method of getting XcomGameState_HeadquartersXCom, updated for changes LW2 made in the 1.1 patch.

Now modifies the base mod's events to have them spawn the LW variant of missions, if applicable.

Getting XCOmHQ should now be more reliable in event functions.

Will use contacted regions only instead of random, if it can't find the region the Avenger is in.
