Review request for Amarok.


Description
-------

This patch moves much of the Equalizer Dialogues internal behaviour into a dedicated object accessed via The::equalizer()*. Any component of Amarok looking to adjust equalizer levels (i.e. The equalizer scripting support I'll resubmit some day) should use this interface.

I'm considering as my next steps, merging the EqualizerPresets class with the EqualizerController class and possibly removing dependence on AmarokConfig to make the actual changes..

*The equalizer dialogue is accessed via The::equalizerDialog()

Testing
-------

Checked that Amarok compiles and that the equalizer dialogue still works. Found that enabling/dis-enabling the equalizer forces the track to freeze or restart. Pressing stop and then play will make it continue with the correct preset enabled.


Thanks,

Ryan McCoskrie
