Detailed analysis of production let us found and fixed several problems:

Depletion reduced final production, not the basic.
PFC gave multiplicative bonus not from basic production.
For each production run, we have added the rounding which will allow to count the final production correctly.

Also in the production we have added display of bonus from sand, moist and gas planets.

Calculation of production was also fixed. Thanks to the use of bonuses xerjs start to contaminate buildings a little bit faster.
