A series of small buffs to Enforcer to make it more usable as an anti-unit bombardment ship.

10% turn rate buff.
10% fire rate buff.
5% range buff (660->690)

Halved flight time so it will not overshoot as much when aiming at aircraft or gunships. Still is more than enough for normal use.

Fixed the center offset gadget (it was taking position relative to base position, not model defined mid position).
Fixed some sea related hitvolumes.
