			Note that this still keeps the old behaviour of putting things in std by default on serenity so the tools can be happy, but if USING_AK_GLOBALLY is unset, AK behaves like a good citizen and doesn't try to put things in the ::std namespace. std::nothrow_t and its friends get to stay because I'm being told that compilers assume things about them and I can't yeet them into a different namespace...for now.
