Slug field update

This is a maintenance release to address a change in the Slug field. This package now requires an updated version (^1.2.3) of the slug field to ensure this change does not affect the permissions tool.

Previously the slug parameter would accept the name of the Slug field, but it now requires the attribute name. Note that if you are using the slug field elsewhere in your code you may need to check compatibility.

v1.0.8
