Print debug output with gdDebug() instead of av_log()

Browse source 
Users can enable or disable av_log() output only by inserting a call to
av_log_set_level() and recompiling GoldenDict. Blink browser engine
shipped with Qt WebEngine sets the log level to AV_LOG_QUIET in
chromium/media/base/media.cc and thus disables all output. So
GoldenDict's custom AV_LOG_INFO messages are always printed in the Qt
WebKit version and never in the Qt WebEngine version.

In contrast, users have many ways to enable or disable QDebug output
without recompilation since Qt 5. Furthermore, GoldenDict's command line
option --log-to-file allows to redirect gdDebug() output to a log file.

The two messages printed via av_log() are clearly debug messages,
because they are printed each time a word or a phrase is pronounced.
