; WHO  : ItemDrop::CItemDropManager::calcRank((unsigned short, int))
; WHAT : Override the chest quality you get when the game initially decided you get no chest at all
;      : It's a bit tough to explain, but the function calcRank does this:
;      : 1) Calculate luck for gold chest, if success exit with gold quality (1), else process next step
;      : 2) Calculate luck for silver chest, if success exit with silver quality (2), else process next step
;      : 3) Calculate luck for bronze chest, if success exit with bronze quality (3), else process next step
;      : 4) No chest at all, exit with no chest (0)
;      : --> The mod below only changes this last step. So even if you put value 1 (gold chest), you'll still get a silver chest if the game succeeded the step 2.
