Merge pull request #148 from squito/include_appId

Include appId in executor cmd line args

add the appId back into the executor cmd line args.

I also made a pretty lame regression test, just to make sure it doesn't get dropped in the future.  not sure it will run on the build server, though, b/c `ExecutorRunner.buildCommandSeq()` expects to be abel to run the scripts in `bin`.
