Changed
* Small improvements to the looks and usability of the fleet support ship management interface.
* Bonuses/penalties for highest/lowest contributor in votes are now integrated over time instead of only checking the final votes of each empire. The vote tab displays which empires are currently considered highest and lowest contributors.
* Ship designs are now based on a static hex size with a limited amount of space available, instead of stats scaling based on the percentage of the ship covered. This invalidates many old ship designs.
* Removed adjacency hp bonus from armor.
* Armor on the outside of a ship does not count towards ship interior space limit.
* Flagships and defense stations are now in separate quickbars instead of together in the fleets quickbar.
* Peace proposals now use the treaty system.

* Planets now go up to Level 5, resource requirements for level 4 have been lowered.
* FTL Crystals are now a scalable resource that provides more FTL/s as it levels up.
* Completely rework the layout of technologies in the research grid.
* Changed the bonuses Zeitgeists give to the highest/lowest contributors in the vote.
