Fix bug with 'Haggling' prestige ability always acting as if it was level 1 even if you had 0 or much more.
Fix bug where 'Haggling' and 'Job Point Gain' prestige abilities didn't show what they actually did numerically in the UI.
Make job point gain prestige ability more expensive and weaker so it doesn't dominate the whole endgame.
Scale back factory power a little bit, it was too powerful.
Fix 'Scientific Insight' building to be considered a military upgrade that recalculates push % and gold/exp farm rate, because it is.
Fix visual bug on Science tab that always claimed your science was full.
Reduce ship mark bonus scaling of library a bit, it was too powerful.
