Update 1.58: Monitary System Balances

Hey Everyone, Today I have some balance changes to the unit purchasing algorithm as well as some balance changes to wages and home desires. As far as my testing has gone, this has created a much more consistent outcomes from the unit AI's. This patch is directly based on the feedback of users, so make sure that you let me know if you think something is not working properly. Because if it is a bug, or not working as intended then I can fix it ;) Patch Notes: - The purchasing algorithm has been substantially updated. This should produce more consistent , and more accurate, purchasing choices for each unit. - Merchants are now taxed at a 35%/40%/45% rate based on house level, up from 30% at all house levels. - Bowyer base wage increased to 8 from 6. - Pottery workers base wage increased to 8 from 6. - Butchers base wage increased to 8 from 6. - Furniture worker base wage increased to 8 from 6. - Tailor base wage increased to 8 form 7. - Water Engineers base wage increased to 14 from 10. - Pottery workers now want level 2 housing up from 1. - Wine workers now want level 2 housing up from 1. - Local Merchants now only require level 2 housing down from 3. - fixed a small bug with extra people being lumped into the "Desires Food Variety" category, this seems to account for about 5-10% of the number you use to see here... - Updated the French text for the new tech options (still need German translations if anyone is interested in doing it).
