This lot of changes brings forth the following:
Sets up a "default" set of compiles that are the minimum needed for
maintain_area.sqf and custom scripts to utilize the gem based currency
that @icomrade added.
maintain_area.sqf: This will now utilize the gem based currency system.
Removed the redundant Z_Vehicle and replaced it with the Epoch built in
DZE_myVehicle
z_at_buyItems: Code tidying and optimization
z_at_checkCloseVehicle: Tidied up the code since removing Z_Vehicle
allowed us to remove some now useless code.
z_at_getVehicleItems: Removed the nearestObjects check for your vehicle
since we now do z_checkCloseVehicle on Advanced trading start up.
I don't think we should allow selling backpacks from vehicles because we
can not get backpack contents.
We can only remove all backpacks with clearBackpackCargo and then add
back new empty backpacks for ones that weren't sold.
This means players may unintentionally wipe all contents of all other
backpacks in their vehicle when they only want to sell one.
Thanks @AirwavesMan for catching this.
Also made changes discussed in #1718 @oiad
