void CMap::DeleteTakenItems()
{
	// There are going to be items on the ground that we want to pick up, but
	// we don't want these items to still be there when we come back to that map.
	// To make sure they are gone when we come back, we assign an action key to
	// each item that we put on the map.  Then, when we load a map and HandleMaps()
	// is called, this function is called to delete taken items.  What we do is just
	// go through the items on the map and check to see if their action key is
	// already set to true (or 1 - we use numbers instead of bools for more functionality).
	// If the item's action key is already set, then we delete it from the map.
	// Whenever we pick up an item it's action key is set.  When creating your maps
	// you need to be sure and give an item an action key, or else this won't work.

	// Go through backwards for all of the items and see if they were taken already
	for(int i = (int)m_vItems.size()-1; i >= 0 ; i--)
	{
		// Get the current item
		CItem *pItem = &m_vItems[i];

		// Check if the item's action key was already set (meaning taken), if so, erase it
		if(g_ActionKeys.GetActionKey(pItem->GetActionKey()) != 0)
			m_vItems.erase(m_vItems.begin() + i);
