Finalize the verification logic for inventory

Browse Source 
Move the ValidateEnabled check to the top to completely disable validation -- it is recommended to actually use the validation. This should work perfectly for everyone, assuming you haven't corrupted the region we're validating.

Game data structure stores as follows:

Item[20] bag;
u32 bagCount;
sbyte[20] binds;
Item[20] pocket;
u32 pocketCount;
sbyte[20] binds;

count is 0,10,20 depending on unlocked, and binding is -1 or 0-7 depending on where the item is bound (item quick use wheel)
