inversed a3

1. torn down the wall that used to separate 2 computer room in the middle, layout changed accordingly
2. simplify handrails, remove the ones that are in the way
3. change some health/ammo supply packs
4. add 2 one-way shutters to the air-vent to prevent Flag-running-Jumper classes (Soldier, Demo and Scout) from getting away too easily
5. add another one-way door in between spawnroom and the sneaky route that leads to the intel room

New mid

One-way door

scaled up the map (about 64-128hu for each area)

due to feedbacks express dislike towards the middle area, I've decided to completely remove them by merging the 2 rooms to each team's attacking route, giving Attackers more option.

added one sneaky route that connects directly to the lower part (under the bridge) of the intel area
