BotAimAtEnemy
MCG - FIXME: This is not set up at all correctly in the following areas:
Needs to consider if weapon is an alt weapon for aim and accuracy as well as functionality
Need to consider range?
Grenade Primary and alt as well as Scavenger alt need to take into account gravity
Needs to pick our new weapons correctly to determine which ones they should:
lead with (projectiles have speed)
decay aim purposely (instant hit weaps)
shoot "around corners" (bouncers, mines, splashdamage?)
