coupling tech

tech: crystallography - convert all your research into 0.25 coupling per research
tech: residual dipolar coupling - cancelling field gun or tech gives +0.5 coupling
tech: fine-structure constant - +6 coupling, eject this tech if you take damage
coupling for cloaking field now gives +33% ambush damage
  tech: ambush removed
coupling for time dilation now gives +25% longer time dilation effect
  about +2 seconds
coupling tech isn't well balanced yet, so give me feedback

non-unitary operator renamed to Hilbert space
