No more `@ingroup`s.
I believe for what i want to do, `@name` probably works better, it
separates stuff out right in the `AOClient`'s documetation page.
Furthermore, I also documented two `Q_ENUM` macros with the most basic
'duh'-kinda documentation, since Doxygen complained that they aren't
documented.
This allows people who grab the git repo to be able to immediately use
the Qt help files for Akashi, without having to build them and needing
`qhelpgenerator` or even Doxygen.
