Change list:

• Yor improvements toned back a bit, Collectives have an increased maintenance, but are still cheaper to build than they were.
• Logistics, miniaturisation and manufacturing techs moved to later positions in the Yor tech tree.
• Revised Yor/Iconian starting weaponry and research time.
• Also, made Mass Drivers or Ion Cannons research a bit cheaper because it seemed totally overpriced in comparison to Yor or Iconian mass drivers research.  That basically affects anyone who is not Yor or Iconian.
• Also adjusted cost of Technology Progression II in Terran tech tree to make it cheaper, redistributing TPs back to techs which come after it.
