zoltanvb 2ca973770f Fullscreen refresh rate improvements 
Handle refresh rate as float in general, and add also extra
attributes (interlaced, doublescan) for video modes.

Make it possible to select exact mode (interlaced / doublescan modes
will not be selected), and allow close matches such as 49.5 Hz
for PAL 50 Hz.
