ZIpped publish over the wire sends zip file twice instead of once

3) An error in WTPZippedPublisher which sent the zipped archive to the remote machine TWICE unnecessarily.
4) Slightly enhanced API (added api, none changed or removed) to allow easier access to the deployment per-module preferences

To reproduce, well, you'd have to use breakpoints really. Inspecting the progress monitor won't do much, because it will still look like it's sending the same file. It will be hard to tell when the first transfer has finished and the second began.
