"GuidedMissileWontUnlock"

Here's an old one that I believe Mr_Molez had on a private site, but I haven't seen it anywhere else so I'll post it here.

Normally, when one dies after shooting a guided missile, the missile no longer tracks the target. This cheat is listed as one of the "Subtle Cheats" of BZFlag, and what it does is it continues to track the target, even after dying. Here's how to do it.

In LocalPlayer.cxx, find this line:
target = NULL; // lose lock when dead

And delete it.
