Committed: Fixes to DruidAwarenessEnemyList.uc

There were problems with vehicles. There may still be on PvP maps (opponent vehicles may not get an awareness bar), but I was noticing an issue with people in vehicles being added to the enemies list when they were driving certain vehicles.

It turns out that there's an issue somewhere in the core with the teamnum somehow becoming erroneous (255, which is usually reserved for non-team, DM games) when someone is driving most vehicles (the tank seems to be somehow immune to this issue).

I'm somewhat concerned that it's possible a vehicle reports "teamnum 0" in certain cases where it shouldn't ... but at least in the next build the big bars on VINV matches will be gone (you'll still get the standard vehicle health bars that you should get).
