duplication mods

all bot upgrade mods are improved by about 33%
mod superdeterminism - spawns 6 mods  (was 3)

mod: futures exchange - canceling power ups increases duplication chance by 4%
mod: monte carlo experiment - spawn 2 mods, but you have a 50% chance to lose a random mod
  requires duplication mods, not available in custom
mod: exchange symmetry - spawn 1 mod with double your normal duplication chance
  requires duplication mods, not available in custom
