cantata/devices/deviceoptions.cpp
rezodlub e8cc1ab8ef Fixes: 
empty folders on MPD side (crash inserting/removing to/from model)
usage of sys/time.h changed to QTime
no unistd.h in Visual Studio
if QT was build without SSL support, there is no QSslSocket class (at least in 5.6 and 5.8)
missing strncasecmp in Visual Studio
utime.sys is actually sys/utime.h in Visual Studio
