QuiverBow

- Made a whole bunch of adjustments and enhancements to the Arms Assistant
-> This includes a better targeting module (it's now able to see through glass and can fire with more accuracy at longer ranges)
    -> By extension I limited their firing range via config to 32 blocks. You can disable this at your own peril
    -> It does not yet lead targets, so circle strafing continues to work for now
-> They can also now hold onto any item. Whether or not they can use it is an entirely different question.
    -> Added a storage upgrade, which lets them hold 8 instead of 4 items
-> Added the ability to replace empty magazines by using a new magazine on them, to make reloading them easier
    -> Only happens if there's no space to add more items
-> Completed their leg design, making them capable of basic movement if upgraded
    -> The AA can be instructed to "STAY" (Will try to compensate for recoil) or "FOLLOW" (the owner) via the written book
-> They can also now be instructed to "TARGET FRIENDLY" and "INJURED ONLY". Use at your own risk
-> Speaking of risk: A second weapon rail has been added to enhance their fire power
-> Added the Arrow and Dragon Mortars to the list of items that can be reloaded
-> Fixed it using up items from players in creative mode
- Fixed the Auto-Crossbow not unchambering after firing
