ebayShopper 42e00475d6 Add sender verification to publish and swap object
Continuation of 8035df0

This is important to have on publish to identify cheaters who spam
create objects in the database or create objects with bad inventory.

- Renamed variables to backport to vanilla
- Removed % and & due to code filtering in publicvariableval.txt

Changes in modular_build.sqf were the same as player_build.sqf.

Tested with building, upgrading buildable/vehicle/tent, downgrading,
buying a vehicle, destroying tent and removing an object.
