All action icons for each class/job are blended together to create new backgrounds for each job/class icon

All action icons for each class/job are blended together to create new backgrounds for each job/class icon. Blends are done by taking the average RGB values at each pixel across all actions. If a job has a parent class (e.g. WHM/CNJ), both the job's and parent class's actions are all used for the final blended icon.
