scrap configurable PercentScoreWeight, GradeWeight

Having these "configurable" in the Operator Menu would likely lead to more confused users than happy users.  I have no intention of bundling Pump Pro or SM5 grade graphics; ITG graphics will always be used.  This is arguably less flexible/more cut-and-dry, but that's not necessarily a bad thing.
comment out UnlockManager in Metrics

...but don't remove it, so that it can possibly serve as an example (or reminder for a future me).
