Keep a Scalar Config Option's Value When Deserializing Fails

A failed stream extraction writes 0 into its target, so Float, Int, Percent and FloatOrPercent options were overwritten before deserialize reported the error, and Point/Point3 kept a partially scanned value. Parse into a temporary and assign only on success; FloatOrPercent sets its percent flag only then too.
