working on the inventory and item functions.
working on inventory stuff.

I still need to actually add a pointer to the player's inventory to the openInvs[] array so that the evaluate_inventories() function will register it.
getting the inventory functions working. Next up: getting point and click stuff working.
getting the inventory working. still needs work.
inventories are making major progress. Display and movement of inventories is working pretty well at this point.

Having multiple inventories open at the same time is working fairly well so far.

.gitignored the debug and error text files
Made inventories jump to the foreground immidiately when clicked.

when an inventory is clicked on now, it will be automatically relocated to the top of the inventory stack. That means it will be "in front of" the other inventories.
