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.
