Fixed my bug in testing.  Minus-sign (-) vs. underscore-sign (_)
made my test case fail because I was looking for the wrong one.

I've changed this to only use dashes.

Next challenge is to actually figure out a functional test, and to see
about importing the grok rules that we have to help with decomposing
java stack traces, and also minimize the gunk in the json that we're
currently sending to loggly.
