Completed Amazon S3 and Rsync support

Final commit from this branch at least, now both Amazon and Rsync
support is included. This commit contains most of the Rsync support as
well as some other nifty things:

* Completed the index.js commands and such needed for this change
* The package.json and gulpfile.js now contains conditionals from Yeoman
so it only creates the needed packages and commands
* Updated the gitignore to contain the information for the rsync file
* Added the rsync-credentials.json file
* Updated the tests accordingly
