Make Compatible with API v1.1

I have updated my copy of Keynote Tweet to work with Twitter's API change and pulling here to share

do shell script "twurl -d " & twitter_status & " /1.1/statuses/update.json"

FYI, The Mavericks OS X update is generates errors with this script, and will take some more script edits to fix (I have not yet updated my OS)
