We don't need to make it THAT verbose. But inserting the module name makes 
sense, because the "official" include is <QtModule/header.h>.

I'd also suggest we shouldn't have two header.h in any of our modules, to make 
sure that if someone did #include <header.h>, they wouldn't get wrong the 
wrong one, ever.
