Some bugs about region Elllin Forest

[yuxaij]

1. Please replace java.lang.Math.min with Math.min in the following four scripts:

• npc/2131006.js
• npc/2131005.js
• npc/2131001.js
• npc/2131003.js

as they attempted to call the min func with an integer and a division expression, typically java.lang.Math.min(300, cm.itemQuantity(exchangeItem) / 100).
A simple script to search java.lang.Math.min/max in HeavenMS/scripts showed that only these four had the problem.

2. Line 116 in npc/2133000.js (EllinPQ's NPC script)

cm.gainItem(1032101, 1); 

sends an non-existed equipment to the player and then cause a client crash when the player open his equip inventory.
