[Item Creator and Entities]

AIS now allows to spawn items as entities in the world thanks to Item Creator (use AIS_ItemCreator to open up a SpawnMenu!).
They are floating above the ground a little bit, bounce and can be picked up with your USE key.

[Drop Inventory]

With AIS_DropInventoryOnDeath (0/1) and AIS_DropOnlyEquipped (0/1) now you can enable dropping EQ on death! Additionally you can set that only EQUIPPED Items are dropped, not your whole inventory!

(This feature is turned off by default.)

Now they stay a little shorter, added little circle timer to show how long they will stay.

Updated Summary in Inventory Panel to show better stats when Realism Mode is enabled
