The following changes were made for this release: added a convenient way to run scripts without having to use the text entry box (saves typing); added tool "roll-ups"; added a l-systems python script; changed the way in which texture names are stored; texture names are now relative to the model's path, not absolute; fixed many bugs (some show-stoppers); rewrote some of the dialogs; added texture loading for wavefront files; began work on loading/editing/saving "materials" (emission, specular, etc); added drag-and-drop loading of models.  New documentation was added for the scripting stuff.
