I was fiddling around, and compiling in the moc-generated code 
fixed the vtable errors.

It was still complaining about `SetAppAtrributes`. Removing the 
function allowed it compile, but then I just get a segfault when 
trying to run it, which I have no way of understanding how to 
begin debugging. :|

I might just fall back to making the Qt the frontend, with the 
Dlang code the backend. Sounds less messy. :(
