[PATCH] Turn off Qt including the C++ Standard Library headers

[Thiago Macieira]

We don't use any of the Standard Library features or classes in
Subsurface, except for three uses of std::sort, for which I added the
necessary #include.

It's always a good idea to include directly the headers you want,
without relying on indirect inclusion

On my machine, the build time dropped from 16.96s to 13.38s or a 12%
improvement.
