Subject: Issue #638 - Part 6: Fix up remaining references - Refactor
 _tabAttrModified to accept two parameters - Modify consumers of
 _tabAttrModified to pass details - Add missing _soundPlayingAttrRemovalTimer
 field - Add missing checks for mute/unmute around the tab browser - Tab sound
 icon should inherit 'selected' attribute instead of 'visuallyselected'
