Use rsync for all transfers

[jschewebbn]

The ssh maintainers have deprecated the use of scp. By removing the use of scp there is no longer a need for a cipher argument.

Issue #4, #12

Thank you for your commit. I think a better approach to this is to make rsync an option, and the preferred on, rather that going straight to no scp, as it is only deprecated at the moment. Also requires rsync to be installed.
