The qcam log prints one message per frame, which is pretty verbose. This feature is useful for debugging, but not necessarily as a default option. Silence it by default, and add a -v/--verbose command line parameter to make the log verbose. While this could have been handled manually by checking a verbose flag when printing the message, the feature is instead integrated with the Qt log infrastructure to make it more flexible. Messages printed by qDebug() are now silenced by default and controlled by the -v/--verbose argument.
