Automatically generate Watcher's Eye

• 1. Generate variant names for the dropdown
• 2. Support legacy mods
• 3. Add wording changes to ModParser.lua (e.g. "increased cooldown recovery speed of Movement Skills" became "increased Cooldown Recovery Rate of Movement Skills used" at some point)

There are a few mods that are excluded, which may be legacy, but I can't search them on the trade site, so I'm not sure.

reduced Reflected Cold Damage taken while affected by Purity of Ice
reduced Reflected Lightning Damage taken while affected by Purity of Lightning
skill effect duration while affected by Malevolence

I ended up using the same labels that GGG uses for their Ids, but sometimes they can get too long for the box. Let me know if I should do some common substitutions.

Added all the legacy mods, however they currently don't show up next to the current form of the mod, and the label doesn't match the auto-generated label either. Since this is a low-priority issue, I may properly fix it before removing the WIP label.

This is ready for review.
