Very minor correction for README

[RYFN]

set the USERNAME, PASSWORD and HOSTNAME variables to the values shown in 'Username', 'Password' and 'Live Feed Topic'

Should read

... to the values shown in 'Username', 'Password' and 'Messaging host'

[codebox]

also the port number may have to be changed, the default 61618 was incorrect and I had to change it to the value shown in My Feeds which was 61613
