Configurable Refiner 2.1.1

This is a configurable refiner that I made after reading the request from this topic.

It contains the following options (all of them configurable):

• Normal refine
  
• Refine N times at once (It's possible to allow this for a different group)
  
• Set different zeny and item requirements based on item's WeaponLv field
  
• Display information about the refine like: the safe refine and the chance of the next level.
  
• Allow the usage of items that increase the success chance
  
• Allow the usage of items that avoids the item from being destroyed when the refine fails
  
• (2.0) Ask if want to use items to protect / increase refine chance
  
• (2.0) Define custom effects when refine fails: stay as is, decrease one level or go back to +0
  

Everything is configurable at the end of the script.

I made some tests and it seems to be working correctly, if you run into any bug or wants to suggest a new feature, please let me know and I'll see what I can do.
