Edits to Avian & Bat
Added power "flammable" to take extra damage by fire (with special effect)
Added power "fall_immunity_or_death" which negates fall damage completely until it doesn't (>20 block drop)
Added power "fox_jump_height" which boosts jump height by a bit, by now unnecessary though thanks to pehkui commands not using base.
Added power "blinding_lights" which will make you blind when exposed to bright lights but only if you're not wearing a helmet.
Added power "night_vision" which is toggle-able, drains hunger when used. Could use a rewrite into an "origins:multiple" but good enough for now.
Added power "pumpkin_hate" which makes pumpkins and pumpkin wearers invisible to the viewer.
Added power "dark_sleep" which allows sleep only within a certain darkness.
Added power "standing_invisibility" which is currently unused due to being quite OP. Could use a timer before it activates.
Added power "reverse_logic" which is still buggy and needs work.
