[dev1017] Suggestion for Spiritbond gain, Optimal and Favored only

Recommendation to have Spiritbond to increase only when the optimal rank and favored class is met on the item.

Theory: May encourage players to choose their gear closer to their level and more suited to their current class and eventually turn that gear into materia.

agreed, also they should only increase if the person fights, makes, or harvests something that is close to their rank. that way someone wont take high ranked gear they want to become materia, put it on a low job and grind on r1 mobs till it gets full spiritbond
