Why do such thing? Adding a `using namespace std` in a common header seems
like a terrible idea to begin with. You should import namespaces only when you
need them, and as much scoped as you can. Or just using what you want (`using
std::cout` if you only use that). Seems a recipe for future name clashes that
will give strange compilation errors if you use reasonably name variables.
Including all the Qt headers is something that I don't understand either. Even
with precompiled headers.
