There is no point in having two variables for the same purpose.
It is also pointless to keep an action count tally like r_action_count
was doing, since it is only ever checked for being 0 or 1. Any count
higher or lower than that is irrelevant.
I will make this change in vanilla too.
No reason to use spawn here. Spawn can have a delay. Since
fn_selfActions runs faster it can register the vehicle as still locked
or unlocked after you clicked the action.

Made vehicle gear always accessible from inside.
Also added optional variable to prevent stealing from backpacks by
non-friendlies at traders. Thanks to @maca134 for the method.
