New feature: Redstone Magnets

New feature: Physics Assembler

Added physics assembler and assembly gauge
Assembly gauge can be used to select a region of space to be assembled
Physics assembler assembles the region defined by inserted assembly gauge, when powered by redstone signal

Added lodestone tracker block
Lodestone tracker outputs redstone signal based on where the inserted compass points

Added 4 lenses: optical lens, fluid lens, focusing lens, invisibility lens
All lenses can be inserted into both optical sensors to modify their behavior and appearance
Optical lens is used to craft other lenses. It can also be colored with any combination of dyes to change the color of the optical sensor beam
Fluid lens allows optical sensor to detect fluids
Focusing lens doubles max raycast distance of optical sensor
Invisibility lens makes optical sensor beam invisible

Reworked thruster particles to correctly collide with world geometry. Also changed their appearance
Added Computer Craft compatibility for most blocks
Added datapack support. Now fuels and their parameters can be defined inside a datapack
Added turpentine, a new built-in fuel that can be used in thrusters
Added configuration option for thruster particle amount
Lowered the default optical sensor raycast frequency to happen once every 2 ticks

Fixed thrusters unconditionally emitting particles after being unloaded
Fixed thrusters not updating immediately after the redstone signal power has changed
Fixed compasses not behaving correctly when their target is on ship if VS Addition is not present
Fixed thrusters, optical sensors, and magnets not responding to being rotated by create contraptions
Fixed incorrect thruster uv and texture
Fixed thruster particles incorrectly inheriting velocity of the parent ship
Fixed excessive blockstates
A bunch of other fixes
