Merge methods "rsync" and "dump"

[fbatschi]

Methods "rsync" and "dump" are basically the same, both use rsync - the only difference is the direction they transfer files.

This can simply be handled with a config variable.

Still the method is different, probably the new origin will handle this. method deploy and dump will be renamed to rsync and the the origins can be remote and one of git, filesystem, db (for the local target)

Still in design phase for the new "one to rule them all" sucker
