turned it into a "bot" to show how to run them in a couchdb

fixes #83 !! @hisakonog @kedersha @louisa-beilig @jdhorner @senhorzinho @gretchenmcc @trisapeace @ymanyakina here is one bot style that we have been using to clean up data...finally checked into the codebase for building more bots.

this style of bot is a cleaning bot, it iterates through all the datum in the corpus, and transliterates the utterance line from syllabics to romanized characters (if it already hasnt been romanized), it also reports its activities to the corpus activity feed so that users can see what has been going on, and it also adds a  comment on the datum, saying that it "passed through" and made modifications :)
