Implemented correct refine success rates above +10

- Refine rates above +10 are updated with the official values obtained
  from Aegis. Note: There are no safe refines above +10 anymore.
- Corrected the above +10 refine NPC to decrease the refine level by 3
  in case of failure, according to what observed in Aegis.
- Special thanks to malufett, Ind.
