Update a wide variety of unique items

[Lothrik]

I'm slowly going through various different uniques — verifying and updating their mod text and other properties as required.

All race uniques, belts, body armours, and shields are updated to match current in-game modifiers and mod sorting. I'll probably update more uniques later, but this should be a good stopping point for this PR.

Some updated wording on uniques may result in the mod parser needing changes.

A few issues with mana reservation legacy mods, and one more typo, but otherwise looks good!
