v0.10.2 - New way of counting production

Added a new way of counting production: count production of all artisan pops, RGOs and factories. Results are a little different, noticeable difference for precious metals production. Notice that it is still not real GDP, but just total supply of all goods.
The new count is under 'Real GDP' column, added for comparisons with old data.
In v0.11 those two GDP fields will be replaced by true GDP.
