- Launcher now creates its TurboVNC connection (CConn) instance much
  earlier, so that the TurboVNC options dialog can use the
  OptionsDialogCallback methods in the CConn instance.
- The CConn class's constructor has been split, so that it is
  possible to instantiate the class in a minimal way when the
  Launcher first runs (to enable the OptionsDialogCallback
  methods), and then run the rest of the initialization later.
- The TurboVNC Options Dialog should work with the Launcher now,
  but it needs further testing.
