Not sure if it actually works as the clients don't render the result
properly (can't see anything where the model should be), but the output
model does import back into blender properly.
Eye position, auto rotation, sync type and particle effects can now all be
edited in blender: both import and export do the right thing. The settings
can be found in the "QF MDL" panel of the "Object" tab of the properties
view.
