Added a merge_params and check_access decorator The merge_params decorator is very simple and takes self._params and merges it with params. It's main purpose is to explicitly mark the views in which it is intended that self._params is merged raw. The check_access decorator factors out the access checking process and passes args and kwargs to the access checking methods. Patch by: Sverre Rabbelier

Prepare access to receive args and kwargs as argument Also use two "magic values" when the sidebar is doing the access checks, this might be useful later. Patch by: Sverre Rabbelier
