Solve: #45 Creation of a 'binary gauntlt' version

After digging around the generation of the jar (more on #45 ), I was able to found that for some reason warble wasn't including the ruby files.

With this PR you can run `warble && java  -jar gauntlt.jar --help` and see https://gist.github.com/sarcilav/5260236

PD: I haven't tested out to much the jar, but I think that having a working jar is a good start
