Some random notes on what needs to be done that probably nobody will
understand but me.

1.  Fix picking of new objects (or figure out a better method)
2.  Fix obj_exists() routine
3.  Fix animation of lights and cameras
4.  Fix the Keyframe Animator so that it can be loaded from a network
5.  Find a way to turn off the trace object, close all popup
    windows, and reset all objects to their proper states in the destroy
    function
6.  Have separate keyframes for each object and fix the file format to
    reflect this.
