Materia Extraction: remove the confirmation dialogue.

Now that extracting materia doesn't destroy the gear item, there is no more reason not to extract materia when a piece of gear item is at 100% spiritbonding, except the likely rare case where the player specifically want to keep it at 100% spiritbonding for non-gameplay reasons. And I would say the convenience of millions of players is going to outweigh the perculiar irrational preference of these players, who can just pay attention to what they extract.

If the dialogue box has to stay, then at least let the confirmation default to "Yes" instead of "No". It is the player's fault for not reading the confirmation. Since nothing is permanently destroyed by defaulting to "Yes", there's no more reason to default to "No".
