Replace Whiskey outpost gamemode with the Last stand mode

The difference would be that the USCM will be using alamayer to prep.
the first map would be a rework version of WO with some LZ’s so marines can drop.
the idea is that in the end Players can choose what faction they will face.
xeno zombie UPP CLF etc…
so basically every map will be a place where the USCM is defending a strong position againt’s all sort of enemies…
