Coordinated Command Blocks
Adds a button to convert between Relative and Absolute coordinates in Command Blocks
for instance a command block at 10, 10, 10 with setblock ~1 ~2 ~3 stone would convert into setblock 11 12 13 stone, then clicking it again would turn the coords back into ~1 ~2 ~3
coordinate conversions are always relative to the position of the command block, so it may have unintended consequences when doing execute positioned or execute at, likewise parameters for the particle command might be interpreted as coordinates (as well as anything else "coordinatey" like text in nbt data might be)
