Added QScreen::refreshRate() to get the vertical refresh rate.
To give applications that want it the option to use a fixed timestep for
animations, and to avoid having values of 60 hard-coded (we have a
couple of those in qtdeclarative/src/quick already), we need to know the
refresh rates of the screens we are rendering to.
