Essences.dat spec overhaul

[eps1lon]

Basically all mod keys fall into two groups:

• displayed mods
• applied mods depending on item class

Only quivers have one field for display and application.

The display fields relate to certain groups e.g. Ranged Weapon or One Hand Weapon. There is some additional squash logic applied e.g. if Weapon and Item have the same mod key only Item is displayed because Weapon inherits from Item. Additionally if Weapon would have a different mod key the Item line would be prefixed with Other. Don't use the Wiki as a reference here because some essences (e.g. Contempt) are not displayed as they are shown ingame. In the case of Contempt essences the wiki shows Shield and Other Armour mods despite them having the same stats and only Other Armor shown ingame.

Currently the following lines are squashed:

• Helmet into Armour
• Gloves into Armour
• Boots into Armour
• Body Armour into Armour
• Shield into Armour
• Armour into Item
• Quiver into Item
• Jewelry into Item
• Weapon into Item
• Bow into Weapon
• Two Handed Melee Weapon into Weapon
• One Handed Weapon into Weapon
• Belt into Jewelry

There might be a single inheritance chain to it but for now this list is sufficient enough to mirror ingame display.

The field names for applied mods regarding 1H and 2H weapons are guessed because there exists currently no essence that applies different mods to maces or axes. I just went with the order in which they appear in ItemClasses.dat.
