Fixes:
- xp and research points should now be correctly added after fights
- spelling and other text tweaks/corrections
- research tabs moved from side to top
- game summary screen text area tweak
- Perun should now unlock properly after unlocking all other gods (so no need to have all gods at level 3). If anyone is still having issues, these should be fixed automatically next time any xp is awarded at the end of a game.
