This was previously used for allowing scripts to set arbitrary values on scripting objects. However, it was used by only a few scripting functions and, as far as I know, no script uses this features. This removes that feature which simplifies the code ade_index_handler of. This also simplifies the code that handles the userdata for libraries provided by FSO.
