Moved AudioDevice::setupWidget into its own class AudioDeviceSetupWidget which logically should belong to the GUI (unfortunately the include structure does not make this obvious). For the ALSA driver there is an implementation AudioAlsaSetupWidget which provides a combo box for selection of the card and device. All other driver widgets have been changed to inherit from AudioAlsaSetupWidget but have not been changed otherwise. SetupDialog has been adjusted to keep a map of AudioAlsaSetupWidgets now.
