[galaxy-commits] commit/galaxy-central: greg: Fix for handling proprietary datatyps definitions in repositories being installed from the tool shed when only datatyes that subclass from those in the Galaxy frameowrk are defined (i.e., there are no proprietary datatype class files for the datatypes). In addition, this changeset now properly handles installing a tool shed repository that included prioretary datatype definitions (they were failing due to a bug in this same method).
