xfree86: Remove TargetRefresh option 

This was a vestige from the days before we'd make the mode list from the
EDID data, and from CRT technology when you could reasonably assume that
higher refresh rates were better.  Also it did not function as advertised,
acting as a high-pass filter instead of a band-pass.

This optional entry specifies the vertical refresh rate that the server
should aim for when selecting video modes. Without this option, the
default is to prefer modes with higher refresh rates.
