Merge pull request #11 from darrenpearson/master

Upgrades to rinSystem, rinApp and K400
Removed unnecessary whitespace
Remove the extra arguments on the 2223 stream call backs.  They aren't present and could mislead.
Hanlde the callback variable arguments better by avoiding the depricated arg variable.
Make the UDP discard function work using large chunks of data instead of single character at a time.
Merge branch 'master' of chef.rinstrumau.local:rnd/L001-503
