SavedCutOffHeadLock reads and writes CutOffLockHeadHeight and
CutOffHeadLockOvercutInches in the WinForms format and converts the
overcut, always stored in inches, to and from each nest's units, using
1.5 in when the saved overcut is not a positive number. The WinForms
CutOffHeadLockDefaults now calls it, with unchanged behaviour.
