Quality/table updates.

With +quality enchants (such as the dan one), dan 3 skill, and reforges somebody made a 100 quality light armor on Ruairi. Since that's most certainly x-grade, I removed the line about x-grade only being available from gachas/events. As far as other bonuses, I'm not quite sure how much contributed to what for the 100 quality item, but I felt some of the descriptions on the page needed updating to account for these things.

In addition I recolored the headers for S, S+, and X to yellow. Traditionally red is used on the wiki to indicate "not implemented" but since it's actually possible in NA red was giving the wrong idea to some readers so it's yellow for "obtainable but you need bonuses".

And last of all, I put the quality numbers on the table for Tailoring just like I did for Blacksmithing... at least, the ones I could figure out from the stat changes. With the addition of the dan enchants for life skills (and things like Daunting dropping from more sources), the question of what "+2 product quality" means (for example) should be answerable by somebody looking at the table.
