Added option to deploy blog locally via rsync

I couldn't get the current rsync-rule to work locally on my box so created a simple option to deploy the blog locally. I do not know if many will need this feature, but I often work directly on my VPS and found it quite useful. SSH-ing onto the same box you are on is not sexy :)

To push locally, just set ```rsync_local``` to ```true```. It will be copied to ```document_root``` and function just as the default behavior.
