Switch the login sound to Phonon directly...for now
Review Request #123834 - Created May 18, 2015 and submitted
With its current architecture, KNotification can cause crashes on logout (and also cause asserts in certain situations, that will be another fix). So in the meantime, this replaces the KNotification-in-a-thread with Phonon directly.
This is exactly what KNotification would do. This is for the time being until the crash on logout is sorted out.
Additionally, this also fixes logout sound which was missing before. This uses normal KNotification as at that point we don't need to be threading or anything, so KNotification is just safe.
Login sound works as expected, logout sound as well. Also tested by couple other people.
