Quick hotfix for some major problems discovered when testing, and a few other minor improvements.

disruptor02

• Fixed being able to walk around combine force field before it's shut down.
• Blocked out the rest of the street leading to the office tower
• A few additional walls blocked out where it could cause confusion about the intended path for the player.
• Fixed random models being transitioned into the next map.
• Made APC weaker. It still takes way to many grenades to kill, and the mounted gun does almost no damage to it. This will be tweaked further.

disruptor03

• Sniper moved to window
• Added lights in spawn room
• Added more health pickups, and a health/suit charger at the beginning of the level
• Added proper ending sequence
• Added "ladder" to rooftop above sniper's perch. (Actually a tiny jump pad)
