1. Add flag(:key) method that you can use to pull values from the command line.
2. Added new "client" environment setting that you can use to change the name of the client output.
3. Decoupled rsync from using SSH. You now have to specify "rsh 'ssh'" in your block to use rsync over ssh.
4. Updated output so stderr only outputs on failure.
5. If the command ran successfully but has no output, we put 'ok' for now.
6. Updated Gem to 0.0.5
