Initial release

This is the initial release of this app.

You can run an rsync command to backup a folder and its files to a remote host.
After the completion, there is an email to be sent to the adresses specified in the config. see rs-backup.sample.json for reference.

The builds are a result of this commit which is tagged with this version but you can feel free to build the binaries yourselves.

Clone the project, run go get and then go build. As you can see we run vgo, so you can do this outside of $GOPATH.
