In some cases, applying the Difficulty Adjust mod without actually
changing any of the settings previously caused the bar in song select
beatmap details to appear red/blue instead of staying white.

This was caused by not accounting for floating-point imprecisions when
determining bar colour in AdvancedStats. To resolve, first check
equality with tolerance, and only then apply blue/red colours if that
equality check does not hold.
