nano bots

catabolism - 2% (was 2.3%) of max health removed
many worlds - spawns 2 rerolls (was 1)
pilot wave field- now has access to several mods that normally require other fields
  this plus the fragmenting block mod are a big buff for late game pilot wave
  let me know if it is too strong

mod nano-scale: bot prototypes - upgrade a bot type and build 2 of that bot
mod nano-scale: bot manufacturing - build 3 random bots
  these mods don't show up in custom
