Two unrelated changes. 1) Return the email address to version 9
clients so they can create a proper .forward file. 2) Add some test code for seeing how feasible it is to do accounts on ops/tips using tmcd instead of direct ssh. Initial results are not good; too many accounts; does not scale well. Going to need a smarter protocol for doing hundreds of accounts, but I will leave this code in place for now. Note, unlike testbed nodes, control nodes must connect with ssl.
