A_JumpIfTargetInLOS - Extend and improve

[DoomRater]

Question with the code- I had reported a seeming range limit on the original JumpIfinTargetLOS when used on a player weapon. Past a certain point on MAP01 my Smart Rifle was not detecting shootable monsters, and I'm uncertain of the issue involved. Thus a secondary indicator was added (a laser beam) to aid in the detection of invisible monsters. Does this code address any of the issues I had there? I need to look for the thread where I posted about this.

As I am not aware of such an issue, I find it unlikely that I have done anything to deal with it.
