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.
Doxygen documentation can be generated by calling `doxygen Doxyfile` in
the project's folder.
Furthermore, a Qt help file is also generated if `qhelpgenerator` is in
the path.
