Introduction
This script allow actors to have attributes that enhance their stats, damage when using certain elements, learn skills.

Features

• custom attributes - each actor has its own attributes
  Attributes give
• stat bonus
• boost certain elements (skills/items damage)
• may actiave a skill while attacking (Eg: You attack a monster, but the skill Fire activated and you use Fire on that monster.)
• customizable attribute picture (24x24)
• Each level you gain points equal to your level (start with 1)
• To level up one attribute one must spend the square of the attribute's current level in points
  (Eg: Flame Mastery Level 1 - upgrade cost 1;Flame Mastery Level 2 - upgrade cost 2 (2x2); level 3 - cost 9 (3x3)
