Since rP25077 persistsmatchsettings got some entries it doesn't need. This is not only bad because the config file is getting bigger/less readable than required. It also causes bugs like the rating bug (rP25859).
The entries where correctly avoided in rP23374 and readded incorrectly in rP25077. More or less implementing the rP23374 behavior.
Explicitly not having the math.round(...) on slider cases (wonderDuration and such), since they already get rounded on set, which decoupled from the gui-object. Solving and jittery gui issue which required them in rP23430.
Moving the playerNames setting into the playerName class. Moving the Rating setting in the Rating class.
