[PD] refresh MIDI device list on run

[Ingo]

You need to refresh the midi dialog by banging this:

[; pd midi-dialog 1 2 3 4 1 2 3 4 4 4(

first 4 = input device numbering (might be different than "1 2 3 4", e.g. "2 0 
0 0")
next 4 = output device numbering (might be different than "1 2 3 4")
#9 = number of input devices (1-4)
#10 = number of output devices (1-4)

Same thing for audio-dialog:

[; pd audio-dialog n1 n1 n1 n1 n2 n2 n2 n2 n3 n3 n3 n3 n4 n4 n4 n4 n5 n6(

n1 = inputs device numbers
n2 = number of input channels per device
n3 = outputs device numbers
n4 = number of output channels per device
n3 = sample rate
n6 = delay in milliseconds

Making an automatic refresh is a bit difficult.

I did it by monitoring the dev folder (or actually I created a subfolder for 
my known devices and I'm monitoring changes with

[hcs/folder_list /dev/"mididevice-subfolder-name"/*] every 3 seconds.

When a change is detected it bangs	[; pd midi-dialog 1 2 3 4 1 2 3 4 4 4(
So all of my "known" devices (by udev names) are mounted automatically. For 
unknown devices I need to execute a [bang] on [; pd midi-dialog 1 2 3 4 1 2 3 
4 4 4(
