Standardized survivor items aka "survivor power"
Instead of having multiple of same item we take one of the versions and set it as the item. Then rework addons to accommodate this change.
Survivor power would be free just like killers power.
Yellow medkit could be new medkit.
Yellow toolbox could be new toolbox.
Yellow flashlight could be new flashlight.
Green key could be new key. (Obviously it would have to be buffed. Ultra rare add on would allow you to open hatch)
Green map could be new map. (Same as key, it would have to be buffed)
