Bootzooka update - fat-jar deployments

Bootzooka is our template web project, featuring Scala and Scalatra for the backend, an AngularJS single-page-app for the frontend, and a joint SBT+Grunt build process.

You can now create a single, runnable jar thanks to the SBT assembly plugin. The fat-jar includes all of Bootzooka's code, as well as the Javascript, stylesheet and html files processed by the frontend Grunt build.

Running a bootzooka-based application is now as simple as:

java -jar bootzooka.jar

You can then access the webapp through http://localhost:8080. Note that if you'd like to create a deployable war file, that's still available. Refer to the README for details.
