[proaudio] add qjackctl 0.2.23

[Harald Gutmann <harald.gutmann@xxxxxxx>]

hello!
i just read that the new qjackctl version has included support for jackmidi.
here is just the quote of the changelog on the qjackctl homepage:

"*Latest release*

2007-07-02 JACK MIDI support debut.
*qjackctl-0.2.23.tar.gz
<http://downloads.sourceforge.net/qjackctl/qjackctl-0.2.23.tar.gz>*

    * JACK MIDI support is now being introduced. Connections window now
      has a brand new MIDI tab, the older being renamed to ALSA, as for
      the ALSA/MIDI sequencer conveniency. The server settings now
      include the MIDI driver setup option (ALSA backend only).
    * Application icon is now installed to ${prefix}/share/pixmaps;
      application desktop entry file is now included in installation;
      spec file (RPM) is now a bit more openSUSE compliant; initial
      debianization.
    * Invalidation of the JACK client handle is now forced right on
      jack_shutdown notification, preventing a most probable fatal crash
      due to jack_deactivate and/or jack_client_close being called after
      the jack_watchdog kicks in.
    * Default font option names were adjusted to "Sans Serif" and
      "Monospace", wherever available.
    * The "keep child windows always on top" option is not set as
      default anymore, because window focus behavior gets tricky on some
      desktop environments (eg. Mac OS X, Gnome).
    * Autoconf (configure) scripting gets an update."


jackmidi would be nice to have, because i think, that ardour's midi
support will depend on it. (but i don't know that exactly.)

have to merge the 99992 version. :)
