added an option to aseqnet to optionally set the midi process name

Browse source 
This option allows to run multiple instances of aseqnet without having
to double check the assigned port number, since each one can get spawned
with a unique name.

-s addr : explicit read-subscription to the given address
(client:addr).
-d addr : explicit write-subscription to the given address.
-n name : specify the midi name of the process.
Default value is either 'Net Client' or 'Net Server'.
-v : verbose mode.
