- Fixed Launcher's interaction with request_visnode.sh.
  - The Launcher now only uses the first part of the request_visnode.sh
    script to return a MASSIVE job number, so now the reqeust_visnode.sh
    remote command is expected to finish quickly, so there is no need
    for a special method for sending the request_visnode.sh remote
    command, and polling for output from that command.
- Added a few things to prepare for interaction with TurboVNC's
    Options Dialog.
