刘皓 b55f6dd1f4
Add more error checking to sandbox bindings
* Added checks for when an incorrect number of arguments is passed to a
  function
* Added checks for when an argument of object type has mismatching type
  (arguments of numeric and string types were already checked for type
  mismatches before this commit)
* Added checks for trying to read certain properties of a disposed
  object
