Replace the compile task with gradle's compile.
Replace the easy-pack maven plugin with gradle's tar task.
Add in a JavaExec task for running within an IDE.

Testing through IntelliJ IDE though tasks are IDE agnostic.

Where the following done:

• Tests. Check all that apply:
  • Unit tests created or modified that run during ant test.
  • Integration tests created or modified that run during integration testing
    (Formerly called regression tests.)
  • Test procedure descriptions for manual testing
• Was relevant documentation updated?
• Were relevant config element (e.g. XML data) updated as appropriate

I rebased this PR on: #47 for simplicity.

The ./war-files/META-INF/context.xml looks like an example rather than something we would want to bundle in any distribution. I'm not sure the best place to put that at the moment. Under an ./examples directory?
