Add explicit access_types from the url This does two things, it reduces the amount of repeated data (e.g., the checkAccess used to repeat the access_type that was already specified in the url). At the same time, it allows for example the 'create' page to push its access_type to 'edit'. Patch by: Sverre Rabbelier
