Bug 1210846 Auto Reset Gain & Eq after each song

-Added a checkbox under preferences->equalizers for enabling Auto EQ/Gain
Reset
-If checked, resets the pregain, lowgain, midgain & highgain to defaults when a new
song is loaded
What about
Label = ``Reset equalizers on track load``
Tooltip = ``Resets the equalizers to their default values when loading a track.``
