WIP: adding an show_inactive operation which should allow you to select which user roles can see the inactive objects of the collection query
Added vocabularies.py with customized Roles vocabularies since the default one from plone.app.vocabularies do not include the Anonymous role and made use of it within the showInactive logic
Added test for the showInactive operation
Added Changes.rst entry for the showInactive operator
Updated branch with latest changed from master
Removed the roles vocabulary from plone.app.querystring opting to use the vocabulary from plone.app.vocabularies as suggested in the comments for this pull request
Added upgrade profile which adds the new operations and fields with the use of registry.xml
Use the canonical Roles vocabulary instead of a newly created AllRoles
Merge pull request #20 from eea/show_inactive

Show inactive parameter implemeted as an operator
