icon-icontrols: split desc file for the two ports if needed

[adcxyz]

the icon-icontrols registers with two midi ports, which makes it necessary to be specific about which port is used for what.
If its modality-relevant midi messages are only on one port, convert the desc to that port only:

idInfo: "iCON iControls V2.00",
// if midi communication is on port 1 in out only, this should become:
(idInfo: "iCON iControls V2.00", sourcePortIndex: 0, destPortIndex: 0)

if there is relevant communication on both ports, the current desc file should be split into two separate files, one for each port, with only the elements that communicate thru that port.
see qunexus for an example file.

I updated current file to use port 1 - hope that works, I don't have the device.
added comment with instructions how to add desc file for port 2 (if it does anything interesting on port 2)

somebody with that device please check :-)

@sensestage - you have one, please check and close if done - thanks :-)

fixed icon-icontrols with an old one (which registers as V1.02):

// correct hid file icon-icontrols-102-hid.desc.scd
// all 3 elements x, y, bt registered
h.free; h = MKtl('h', "icon-icontrols-102-hid"); h.trace.gui;

// correct midi file: in 0 and out 0 are automatched, no multiindex message
m.free; x = MKtl('m', "icon-icontrols-102"); m.trace.gui;

@nescivi :
Please check whether the two files adapted for the icontrols V2.00 work with the device you have:

h.free; h = MKtl('h', "icon-icontrols-200-hid"); h.trace.gui;
// Note that the desc only has layer 1 for now, info on 2-4 is noted, but not used yet.
m.free; x = MKtl('m', "icon-icontrols-200"); m.trace.gui;

Are the midi numbers in layer 1 the same in 2.00 as in 1.02? If so, we can unify the descs.
