Adds support for local syncs of files and folders on the same Windows machine, e.g. cdc_rsync C:\source C:\dest. The two main changes are - Skip the check whether the port is available remotely with PortManager. - Do not deploy cdc_rsync_server. - Run cdc_rsync_server directly, not through an SSH tunnel. The current implementation is not optimal as it starts cdc_rsync_server as a separate process and communicates to it via a TCP port.
