compile fails about spark-websocket

[cswarth]

I fixed this issue by adding the appropriate <configuration> directives to the pom.xml file. While I was at it, I also updated the build to use the latest version of the spark API (v2.5). I had to add an explicit dependency on slf4j-simple or the app would fail at runtime due to lack of a logging implementation.

Sorry about that, I left target out. I just pushed the change :)
Edit: I guess I can migrate to 2.5 while we're at it.
