Storm dependency should have scope of 'provided'

Per recommendation from the storm team, it is best that the jar being deployed into a Storm cluster not include the storm jars themselves.  See the Maven example for more explanation: https://github.com/nathanmarz/storm-starter/blob/master/m2-pom.xml

In this project, it is probably best to declare Storm as a 'provided' scope dependency.  I will be doing it in my fork and will push that shortly.
