Implement GetNumStackedItems

[modawan]

This routine is used to get the number of items in the inventory. On the second level of Endar Spire, there is a terminal that needs computer spikes to overload, and a droid that needs repair parts. Scripts for both use GetNumStackedItems, and there is no way to unlock the door without them.

Workaround: change GetNumStackedItems to always return a value greater than ~8 to bypass the checks.

There is also GetItemStackSize routine, and it is already implemented. Not sure what is the difference between GetItemStackSize and GetNumStackedItems.

Console commands to reproduce:

warp end_m01ab
setposition 76 68 0
autoskipenable 1
autoskipentries 1 1 1
killroom
additem g_i_progspike01 100
additem g_i_parts01 100

Start the game, in the main menu open the console (~), paste commands (Ctrl-V), Enter.
Then try to activate the droid. The last two commands add 100 spikes and repair parts, which should be enough to repair the droid.
