* initial commit, includes
  - xappy: the systray app which marshals tests to vstest as an interactive
    process
  - xappyclient: the cli client for sending tests to the xappy host
* note that there is essentially NO SECURITY imposed on this entire system
  - it's expected that it will run in a trusted environment, ie in a vm
    which your build server can see across the virtual network and which
    is not exposed to the Big Bad World
* add client timeout option
* shouldn't be tracking these
* ignore bin output area
