a5:
* added 6-second setup time, because apparently Special Delivery does that
* fixed the flag return time, it now resets after 15s (thought I fixed this in the last version, apparently not)
* added stuff to the flag pickup zone
* changed the indoor area in the middle a tad
* players can no longer build sentries in the trees
* added delays to more of the helicopter pilot voice lines
* made the helicopter rotors smaller, ya whining babies
* fixed players being able to ride the helicopter (no really, this time it's final)
* fixed the alarm not playing when someone signals the helicopter (the alarm now also plays when the helicopter is close to landing)
* made delays between voice lines longer (was 10s, is now 16s)
* added a couple more voice lines
* downgraded the two ammo packs by the helicopter from medium to small
* removed the Predator audio clip (sorry guys, it was getting old)
* some other misc changes
