Use UTF-8 everywhere possible and only use wchar_t where required.

* This means that all APIs pass byte string types. ALL strings everywhere
  in the entire codebase must be assumed to be and treated as UTF-8 content
  not ASCII.
* Gets rid of all the horrible %hs specifiers that caused warnings on
  linux! Hooray.
* We convert to wide strings, or use wide characters, only when necessary
  to use the Win32 API. Some windows specific code will stay in wide chars
  just for convenience.
* Files are already serialised as UTF-8 strings for linux/windows binary
  compatibility, so this change doesn't break backwards compatibility.
