shifting away from gui driven, more towards randomization managing
object-classes
can do if (x is PersonalInfo7 p7)... for type specific rands, way faster
than doing rand in by the GUI anyway.
p7 & p6 rand is actually the same, no SM specific additions were made.
eventually the other editor-randomizers will be treated like this, and
maybe GameConfig will be expanded to store more persistent string / etc
data.
