Gibs inherit velocity derived from the angular velocity of an MO and their offset from the centre. Scaled by InheritsVel and doesn't affect gibs without offset.

+- Gibs now inherit velocity derived from the angular velocity of an MO. This only affects gibs with an offset, and is scaled by `InheritsVel`.
