1. Slayer support and gamemode tweaks

    Mistercheif1171
    The map now supports all slayer game modes! I have also tweaked the gamemode to experiment with different settings and see what you guys think.
    Changes:
    -Added more power weapons on the map for slayer game modes
    -Increased Grunt health, shields, and damage
    -Decreased elite health
    -Slightly increased elite damage
    -Increased amount of ammo marines have on AR. Makes it a reliable alternative when out of ammo
    -Increased Marine health and damage, but halved damage resistance
    -Changed grenade...
