Refactor functions.php

* Isolate scope of included files
* Load composer dependencies before loading Sage procedural code

Note that scope isolation was originally proposed by @al-the-x in 2014,
and we rejected it at the time. Our theory at the time was that shared
scope might be expected by WordPress developers. But since then we've done
quite a number of things that are atypical of WordPress development,
including our use of namespaces, which in itself is a form of scope
isolation.
