Added AllRolesVocabulary which contains also the Authenticated, Anonymous and Owner roles removed from the RolesVocabulary
Removed ununsed import
Removed Owner roles since it is returned by the call to getPortalRoles and check if the role isn't already added, if a role is already there than we avoid a term value not being unique error
There are now 5 results for the AllRoles vocabulary after the previous commit that removed the Owner entry
Context for the translation of Roles should be the request and not context in order to avoid TypeErrors
Removed AllRoles vocabularies, opting in the end to ammend the Roles vocabularies with the missing Anonymous and Authenticated roles
Merge pull request #9 from ichim-david/master
