new mod - heal: gives heals
new mod - ammo: gives ammo
mod mass-energy equivalence no longer benefits from harm reduction effects,
but it also takes 25% less damage than before
mod - timelike world line gives 2x faster speed and harm immunity when time dilation is active
mod - Lorentz transformation improves move jump and fire speed even when time dilation isn't active
(the same as 1 rank of squirrel cage rotor and auto-loading heuristics)
