Item Modifier Updates: Work on 76+ Armor Equipment

This commit provides basic modifiers for all 76+ armor equipment that is added to the AH if you run the AH Tool. Previously, pretty much none of the 76+ equipment that got added really worked, despite being buyable and equipable, as none of the modifiers were set. Now the equipment is 95% functional, with the exception of some obscure modifiers and latents.

TODO:

1) Modifiers that we don't have implemented yet. There are commented out TODOs noted for these with that value, that we can fill in the number for when the modifier is implemented.

2) Latent Effects

3) Gear Set Bonuses.
