Display active MIDI Port

[Machion]

I use Dosbox on Linux and it was a little bit work to get Midi output working (with fluidsynth+qsynth). It's a little bit unclear that you have to write the actual midi port into the dosbox-conf file. Many guides mentioned it's "128", but not always and it would be great, if qsynth could display it somewhere on the gui, so I don't have to use "pmidi -l".
