Previously, the graphics code tried to set a refresh rate as close to
85 Hz as possible. This led to black screens when the display driver
would report a refresh rate that was not actually supported by the
monitor.
This change also uses the currently set monitor orientation, instead
of always selecting a non-rotated display mode.
This time with more manual checking and using git blame -M -C, so that
a few cases of copied code get a copyright notice corresponding to
their initial introduction.
Using the standard utility function on windows to split the line and the
operating system provided argc/argv on the others.
Also move the function to C4Application. It's not a huge win because the
flags are spread out between C4Game and C4Application pretty evenly, but
eventually most of them should move to a more appropriate place.
