Limit max oxygen tolerance

[Patryk26g]

Brief Description of What This PR Does

This PR:

• limits max value of oxygen tolerance to 10%,
• allows for bigger values when loaded from an older save or different microbe
• changes calculation of optimal UV and Oxygen starting value as previously, when starting multicellular freebuild, the microbe had unnecessarily big tolerance values when organelles added positive effects

Draft for now as I need to playtest it more

Would this limit the slider on the tolerance panel to 8%, or am I misreading the explanation.

[Patryk26g]

It would limit the movable slider, but not the max display value, this one stays at 100% max

[Patryk26g]

It seems that since auto-evo is still run, the begging conditions when player's cell tolerances are calculated are changed (the one read in OxygenResistance = GetAmbientCompound(Compound.Oxygen, CompoundAmountType.Biome)). So oxygen level might decrease, hence the *0.8 multiplication

Shouldn't it be slightly increased instead? Because couldn't auto-evo theoretically cause the world to also get more oxygen thus requiring more protection. I'd like to much more avoid the situation where the player's initial tolerance is not good enough for their environment.

[hhyyrylainen]

This comment still says the opposite (decrease instead of increase), but other than that the code changes now look good.

[hhyyrylainen]

To me it does not look good that the upper bar is not updated to match with the range of the lower bar, I think both sections should have the same max range as otherwise it looks silly like this:
