Creating new drops

[xoft]

I think the last "else" branch is wrong:

amount = math.random(0,2)
if (amount ~= 0) then
  Pickups:Add(cItem(E_ITEM_POTATO, math.random(0,2)))

This checks the amount, but then uses a new random number for the amount anyway; if that results in a zero, it might misbehave.
