Further tweaks to permissions on Debian package build.
- Changed progress dialog's initial status message to "Checking
  installed version of TurboVNC..."
- Temporary status message used to determine size of progress dialog
  has been updated to reflect the current longest status message.
- Size of progress bar is now determined by size of default status
  message in progress dialog.
- Now the Save/Discard VNC session dialog always appears
  after closing a CVL VNC window, even if the user
  specified a display number manually.
- Added IP address of CVL Demo 2 to CVL Host combo-box
- Eliminated original CVL Demo IP address from CVL Host combo-box,
  and made CVL Demo 2 IP address the default for first-time
  Launcher CVL users.
Strip whitespace from username etc.
- Changed "... of 9 nodes in use" to "... of 10 nodes in use".
  Paul is no longer using the 10th Vis node for CentOS 6 testing.
- In die_from_login_thread, displaying an error dialog is optional,
  however, until this commit, the while loop waiting for the error
  dialog to complete was run even if the error dialog had not been
  displayed.  As a result, the progress dialog didn't appear in
  subsequent attempts at running the login thread.
