made better use of Ui::trayActivated() so it can not only display the

context menu, it will also show the app when double clicked.
AudFile::getDuration() and AudFile::duration() can now calculate the
length of the audio based on the rate at which QMediaPlayer calls
AudFile::seek() and the amount of data it pulls at a time. it converts
that time internally to a string, where it is then used to display on
Ui::timeDisp. i've also modified the minimize to tray function as a
feasure that can be turned on/off within Conf and added the needed check
box to the config menu.
