Nature's Aura Plus+

Changelog:

>> New Multiblock: Auric Concentrator! This multiblock runs on aura and features fluid and bonus chance-based outputs, with built-in jei support. (3x3x3 of Auric Oven Brick, built by right clicking with an aura container with enough aura) It is highly configurable via the gameplay configs as well. (Completely functional but internal structuring and textures are still WIP, and has two test recipes for now)
>> Added right-click equip for the Naturalist's Sash curio.
>> Support for more slime mob types for the Offshoot Observer (Slime Aura Gen).
>> Added bountiful ore generation jsons for overworld and nether dimensions, and fixed their weights to the expected default values.
>> All of the aura gen jsons now have a priority system with concatenation of list-based values when priorities are equal. 
>> Added tag based control for what blocks can/cannot be bonemealed due to high environmental aura (w/ config controlled whitelist - blacklist toggling, and configurable aura cost per bonemeal effect instance).

Bug Fixes:

>> Clashing config values' keys have been fixed.
>> Fixed a crash with loot finder staff.
>> Code-proofing against more potential crashes.
