I've implemented a crosshair using the "mark" sprite that shows a
missile lock. The seeker AI is changed so that it loses the lock if the
target is outside a viewing angle of +-60 degrees in front of the
missile, adjusted for warping. If COS_VIEW_ANGLE <= COS_NOTURN_ANGLE the
missile never loses its target.

This can be changed by setting the COS_NOTURN_ANGLE define to -0.17. The
+-90 degrees angle represents a target behind the missile. I'd prefer
the +-90 degree value but you can change if if you want.
