[DAEMON-56] Add "gulp package-bundle" task

The daemon has a gulp package task that builds a distribution tarball which is suitable for distributing on NPM. It is also desired to generate a distribution tarball that contains all the resolved NPM deps. This will probably use something like https://www.npmjs.com/package/npm-bundle to do this. This task will need to be run PER PLATFORM PER ARCHITECTURE and the output will be a tarball with the filename pattern appc-daemon-<version>-<platform>-<arch>.tgz. The script https://github.com/appcelerator/jenkins_dsl/blob/master/jobs/appc_cli.groovy#L124 has some info on using npm-bundle.
