To avoid further floating-point comparison bugs, remove all usages of
Bindable<{float,double}>, replacing them with their
Bindable<Float,Double> counterparts.
Due to using Bindable<double>s previously, song select's filter control
would not apply tolerance when checking IsDefault, therefore wrongly
hiding maps with star ratings above 10.1.
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.
