Fixed situation where broadcast commands from wfview that were echo'd

back to wfview were parsed. Minor change to udphandler.cpp to remove
_sleep() calls (they can be later replaced with either qt's threading
library sleep call, or the unix-native usleep/msleep calls, if windows
has those. Also did a minor thing with a type conversion in udphandler.
