fractorium/Source/Ember/XmlToEmber.cpp
Person a0a205edd8 --User changes 
-Users can now specify animation params on a per flame basis.
 --These get saved with the flame file.
 -Allow for rotating xforms around the world origin during animation.
 -Make the Clear Flame menu item be more comprehensive in how it clears a flame out.

--Bug fixes
 -Fix an extremely rare possible memory leak when using motion during animation, which is never used in Fractorium.
 -Do not skip to the current flame index, or attach a prefix in the Final Render Dialog when rendering an animation sequence.

--Code changes
 -Place all animation params in Ember.
