This merges the public `uiItemS` and `uiItemS_ex` functions into an object oriented API (`uiLayout::separator`), matching the python API. This reduces the difference between the C++ API with the python version, its also helps while converting code from python to C++ code (or vice-versa), making it almost seamless.
