Added file/user resources

Added file/user resources for $root and $user to satisfy Exec dependencies on like 49.  It's looking for puppet resources which ought to exist in this file.  Otherwise the including manifest must define them, which is not necessary IMO.
removed user resource and Exec dependency

User resource is more likely to be part of the including manifest.  Either way, prefer to let it error out than fail because of this resource dependency.
