Subject: Fix the session chimes (and possible stability issue) by removing the
 special audio thread and using the QMediaPlayer within the main thread (no
 stuttering/delays in my initial tests so far). Add a PC-BSD specific routine
 for setting brightness so that hardware brightness controls are attempted
 (through pc-sysconfig) before the software brightness is modified (using
 xbrightness)
