Vault Filters

# Nested Filters
thanks to MaxTheMooshroom for assistance with it

Middle clicking on a nested filter in the UI of a list filter will open its menu allowing you to edit nested filters easier
When editing a nested filter pressing the checkmark will reopen the menu of the previous filter, closing in any other way will close the menu entirely

# New Attributes

Is a faceted "Ability Power" focus (request by Rizek)
Is a retired companion (request by Satanmarks)
Has a max roll legendary (request by Danny)
Has an affix that adds to a specialization of "Fireball" (added to gear and cards, requested by Fishy)

# Bug Fixes
Fixed crash with some added mods on lower version of forge (worked fine with base pack but can cause problems to packs with additions)
Unidentified gear with guaranteed legendaries will now be properly marked as legendary (reported by Lawliet)
Reworked comparison code for clarity, fixed some "at most" and "equal" attributes comparign with atleast (all companion attributes, artifact id attribute and maybe some more)
Switched to better packet usage
