Removal of a superfluous include in AudioAlsaSetupWidget.cpp Removal of the function "bool hasCapabilities(char *device_name)" which was not used anyway. It implemented a test for ALSA device capabilities needed by LMMS (SND_PCM_ACCESS_RW_INTERLEAVED, SND_PCM_FORMAT_S16_LE, etc.). Corrected header name in AudioAlsaSetupWidget.h. Created an implementation file for AudioDeviceSetupWidget to make more clear that it's part of the GUI. Fix build for builds that use Port Audio. The setup widget of AudioPortAudio.h still inherited from AudioDevice::setupWidget instead of the new AudioDeviceSetupWidget.
