support rsync from remote to local

[MacHu-GWU]

fix#26

The method is simple. Just add an argument remote_to_local to transfers.rsync function.

If the flag is True, then switch the source and target in the command template. And use keyword arguments instead of positioning argument style.

Solution:

ifhost.count(":") >1:
# Square brackets are mandatory for IPv6 rsync address,# even if port number is not specifiedifremote_to_local:
cmd="rsync {options} [{user}@{host}]:{target} {source}"else:
cmd="rsync {options} {source} [{user}@{host}]:{target}"else:
ifremote_to_local:
cmd="rsync {options} {user}@{host}:{target} {source}"else:
cmd="rsync {options} {source} {user}@{host}:{target}"cmd=cmd.format(options=options, source=source, user=user, host=host, target=target)
returnc.local(cmd)

@bitprophet Hi, I like your fabric project. I made a little improvement to make patchwork can rsync from remote to local. Please review. Thank you

In implementing this for my own use I combined it with the work on integrating with Fabric => 3.0.0 using #46 (comment)
