This PR is related to https://github.com/apache/storm/pull/1429 but I found
this issue independently, in my local branch, which was a bit outdated. This
patch still makes sense since it gets rid of five warnings that are caused by
having ITridentSpout.BatchCoordinator as raw type. Furthermore, it also prints
more the actual word count output in the example in file `TridentWordCount`
