• bugfix: fixing code that resets tone queue on flushing. A bug was found on FreeBSD: after pressing Ctrl+C, application that wanted to stop and delete generator as part of SIGINT handling procedure, got stuck in cw_tq_flush_internal() function, waiting for tone queue to go idle. This never happened. Resetting all tone queue state variables in flush function ensures that the function completes and returns, and that client application can exit.

• xcwcp: the application souce code files are now ported to Qt5. Build system files have been modified to use Qt5 to build xcwcp. Discovery and adding -fPIC to compiler flags for xcwcp is right now very naive, perhaps that will have to be improved in the future.
