Fixed error using contour level mouse mode in stereo. Mouse modes were not working in stereo because there was no code to choose whether to line up the mouse pointer using the left eye or right eye. So no mouse modes that rely on mouse position over the graphics worked. I made it use the right eye.

A related tip for using stereo. Zooming with the scrollwheel with the Alt key held down will move the model z position relative to the screen. Without the Alt key it scales the model while keeping it at the same depth relative to the screen.

[Tom Goddard]

The first error in the log is a session save failure involving the Symmetry_Manger class. Reassigning that to Tristan who wrote that code. The Symmetry_Manager class either needs to declare it does not save in sessions or it add support for saving in sessions.

[Tristan Croll]

The latest versions of Clipper and ISOLDE no longer cause crashes on session saving, but are not yet fully saved. The atomic model will be returned on session restore, but other Clipper and ISOLDE-specific information is lost. Full save/restore capability will be added in a future release.
