do_item loop upgrade

[TheAdmin33 38]

GMs can use the /i command to create items. Normally, when you use the command /i 27992, it produces 1 White Pearl, and using /i 27992 10 produces 10 White Pearls.
With this update, using /i 27992 10 10 will produce 10 stacks of 10 White Pearls each (i.e., 100 in total).
For non-stackable items, an example command is: /i 19 0 10 (creates 10 units of +9 swords).
