loolwsd: include cleanup and organization
A source file (.cpp) must include its own header first.
This insures that the header is self-contained and
doesn't depend on arbitrary (and accidental) includes
before it to compile.
Furthermore, system headers should go next, followed by
C then C++ headers, then libraries (Poco, etc) and, finally,
project headers come last.
This makes sure that headers and included in the same dependency
order to avoid side-effects. For example, Poco should never rely on
anything from our project in the same way that a C header should
never rely on anything in C++, Poco, or project headers.
Also, includes ought to be sorted where possible, to improve
readability and avoid accidental duplicates (of which there
were a few).
