Allow user to configure BesLoudness

Browse Source 
* Audio HAL turns it on every boot but there's no way to configure it
* Because it tends to cause worse sound quality on devices with bad
  speakers, allow user to configure it
* Apply saved setting value every boot
* Configurable from "Settings > Sound > BesLoudness"
