plugin groupblog, tmp (mam, rsm): some style improvments/fixes: - renamed variables nammed after reserved word/module - removed class variables which are not needed - removed external parenthesis from asserts - in mam.MAMPrefs, removed default value for default argument, as None can't be used - (groupblog) extended docstring for DeferredItems and DeferredItemsFromMany
