Title: Guess x/y FOV/aspectratio from resolution

Added r_aspectratio -1 which means "auto" (as new default).
This mode sets fov_x and fov_y according to screen-width/height.
=> No need to set r_aspectratio manually anymore (assuming your display's
pixels are about square).
The standard aspect ratios can still be enforced as before, though.
