MACHO

tech: MACHO - an object follows you and gives you harm protection when you are inside it's halo

several nano-scale field tech now require some research, and have been buffed
  nano-scale mycelium, ice-IX, missile tech now consume 20% less energy to produce bullets
  nano-scale bot tech: spawn an extra bots

some bug fixes
