Remember values set by -firstOptions, -secondOptions

When an engine announces its option features, and the option name
matches that of a setting given in -first/secondOptions, the engine is
sent hte specified value, but this value was not remembered as current
value (but the latter  was left at the engine-announced default),
leading to inconsistent behavior in the Engine #N Settings dialog.
