Changed the user_to_service mapping table into a model called ServiceUser. When looking at users who have permission for a folder we are only interested in users for a particular service, not all users, so we can use the ServiceUser model to access folder permissions. Added a user_folder_permissions table which contains the service_id, user_id and template_folder_id. There are links between user_folder_permissions and TemplateFolder, and between user_folder_permissions and ServiceUser.
