Updated because of new MCC update

Added cortana dialogue to help nudge players to use the elevator after the power comes back on and replaced one of the phantoms with a banshee so that they would stop crashing into the structure and staying there for the rest of the level.

Changed a grunt spawn point since he wont move due to debris. It was annoying me

Modified a script so that you will always get 4 allies upon returning to the upper levels of the structure after turning back on the power.

Added an additional checkpoint after the initial gate fight, a little more mission dialogue and touched up the return trip encounters

Small tweaks to control room encounter

Added more mission dialogue, added some enemy encounters on the way back up the structure. Also added some more jumphints in the encounter with multiple levels after the first gate fight (where the odsts stop following the player).

Added more pelicans, looking into adding some scripted dialogue. It's difficult to make it fit with lines already found in the game. I also added a couple checkpoints at the base entrance area, it will attempt to give one after dealing with the first wave and one more time after the wraith is cleared while you are nearby the structure. Maybe I will add one more after the pelican drops off ODST reinforcements so people can choose to betray the marines for fun without sacrificing progress in the level.
