ahShop 2 (npc shop system) (updated)

What is new at this version?

1. Fixed a lua error caused by versions of ahshop3 being added to the version by a mistake ( will come later)
2. Added a new feature, so you can place a purchase delay on each items, lets say someone can only purchase a certain gun every 300 seconds)
3. Added a new config option so you can enable or disable purchase delay.
4. Add a new config option to each item, so u can manipulate the purchase delay, on each item.

NOTE: YOU HAVE TO UPDATE YOUR ADDITEMS CONFIG FILE, FOR THE NEW UPDATE TO WORK.
