CathbaldSheilaItems

This is a merge of Sheila's !537 (closed) branch with a bunch of patches Cathbald sent to me along with some edits and additions by me. I did it this way instead of putting it up as a separate MR from Sheila because there are some conflicts with them both changing the same items which this resolves.

As a rule I've been suggesting a few things to people modifying items:

• Mastery bonuses are usually too low, 0.3 is a good number because this is a hyper specific stat and its boring to have it be a low bonus. Most items horrifically overrate how strong this stat is.

• Fixedarts should focus more on doing unique things than being stat sticks.

• Actives are overused. Often they're just contributing to button bloat and aren't even exciting (breath actives and similar). Changing actives to procs is often a good way to fix this. People love procs.
