Gearifiers

Added a blackList config json that lets a user define items that should not get modifiers nor be rerollable in the Reroll Altar. Items can be defined:

• By mod namespace. For example, adding "minecraft" to the namespaceBlackList list will prevent any vanilla Minecraft item from getting or rerolling modifiers.
• By individual mod identifier. This is the id seen with advanced tooltips shown. For example, adding "minecraft:wooden_axe" to the individualItemBlackList will prevent the Wooden Axe from getting or rerolling modifiers.
