Partial revert of: 3aad4b6
Unfortunately this will not support loading external vehicle addons
(with custom UserActions) which we can not include in Epoch. Child
UserActions overwrite inherited UserActions.
Should improve client FPS while still allowing conditions and scripts to
be customized.
Some special vehicles like MV22, UH1Y, etc. have UserActions overwritten
in their configs, so please let me know if you find any others that do
not get the option to repair or salvage because UserActions is
overwritten in their config. I think I got them all.
