Breaks with slackbot

[chandlervdw]

I've got hubot set up with slack but this script breaks the bot, causing heroku to crash.

ERROR Unable to load /app/node_modules/hubot-scripts/src/scripts/karma: ReferenceError: robot is not defined

The karma script has actually moved to it's own package, re the deprecation warning:

karma.coffee has merged with plusplus.coffee and moved from hubot-scripts to its own package. Remove it from your hubot-scripts.json and see https://github.com/ajacksified/hubot-plusplus for upgrade instructions

I'd try switching to that first, and report the issue there if there's still problems.
