Add a verbosity setting to QDebug.

Add setters for an int verbosity to QDebug. The streaming operators
can check on the setting and output more information accordingly.

[ChangeLog][QtCore][QDebug] How verbose a single debug output should be
can now be fine-tuned by setting a verbosity on the debug stream.
