Use zip_rule() for EAR/WAR deploy archives

These build rules allow Bazel to generate the .ear and .war files which
appcfg.sh (a tool that comes with the App Engine SDK) can then use to
perform a deployment.

Included in this CL are configurations for five separate production
environments: production, sandbox, alpha, crash, and local.
