The transformNumbers function was turning m^3 into m^3.00

This lets the volume meters not jitter around, but also lets things that should be fixed precision

This marks the first time anything more than parsing is done to a setting when
loaded or saved. Hopefully floating point errors will not wind up causing problems!

Old saves will have their base production values cleared.

This replaces the old behavior of setting digestion time to 0.

This was because the game threw out all false settings when exporting -
in the past, every checkbox defaulted to false. This was done because
many checkboxes lack default settings of false, meaning their

case - false setting, undefined default - before moving on to the more
general check for equivalence.
