Fixed up some bugs that I previously hadn't noticed...
 BUG FIXES:
    -You now pick up the top item that you see on the ground (if they were
    stacked, you would pick up the bottom of the stack)
    -You don't drop your entire inventory when dropping an item now

NEW BUG:
    -Sometimes kobolds just...appear.  I think it has something to do with
    spawners being on borders
