* sf2Player: retrieve resampling-interpolation from current mixer quality settings

* mixer: made m_writing-variable in fifoWriter volatile
* projectRenderer: change audio-device to file-device from within GUI-thread in order to make slots being connected to sampleRateChanged()-signal being called 
immediately
* audioDevice: made HQ-mode for audio-devices optional
