autonomous navigation

tech: autonomous navigation - drones travel with you through levels and drones reset durability
tech: technical debt - increase damage by 300%, but reduce damage by 10% for each tech you have

molecular assembler now has a higher bullet spawn cap 200->300
  but it increases energy cost per spawn above around 150

fragments are about 15% fewer
thermal runaway is about 40% bigger and more damage
plasma torch: extruder uses less energy
pilot wave uses less energy
