Hide the 'home' field until we have a proper document selector Rather than having a confusing 'home' field that lists all Linkables (in other words, everything in the database), we're better off hiding it for now.

 This module houses the GEOS exceptions, specifically, GEOSException and

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
