still not there: CVWidget:*multiSlotOSCcmds

for OSC-commands with msg-slot size > 1 if the OSC-responder listens to
all addresses in one slot and to a specified address in another
multiSlotOSCCmds should contain the specified cmd being listened from
all addresses not only in 'all' but in all keys representing specified
IP-addresses. Not sure how this should be handled...
