Hiding player while driving

Made critical components less likely to break by just walking

Minor rocket registry fix. Unsure if not putting level. in the registry name had any impact.

Various heli upgrades

Can choose to either start the level with rocket or gatling or neither mech.
Major updates to the helicopter

Fixed the bug with one gatling breaking meaning that neither shoots
They would also both smoke when one broken off
The breaking check with connections didn't work well
If the other side gatling broke both would keep shooting

Moved heli to a more convenient position

Aim spread with gatling is weighed toward the center, but the maximum inaccuracy is increased.
Bug fix: will not shoot the gatling outside the maximum range of shots.

Better spawning
-fixed a bug with collision filters when spawned
-After spawning it looks for stopping movement rather than reaching the ground exactly to start up

-Stronger gatling damage, and deeper penetration
-even deeper penetration when player controlled
-may be worse for frames
