Do not override devicename with incremented jackname when jackname not unique
Alias -jackname to -devicename, and use devicename for jack and alsa midi connection names.
Second pass at creating a devicename for the alsa midi device. This time the devicename is accessible from other files - like jack. If -jackname is provided - then that will be used. Otherwise devicename, or a default name will be used. Removed the silent setting of the Jack back end that was hidden in the -jackname arg check. Use the -jack flag instead.
