[1.0.0] Artillery continues to fire on enemies that move out of range

[calcwizard]

While testing viewtopic.php?f=7&t=91497, I discovered that artillery turrets continued to fire on the Spidertron after it left its range, either moving too far or too close to the turret, even potentially causing it to shoot itself to death. This bug also exists when teleporting any other entity that has been targetted, where the artillery turret will continue to fire after it is out of range. I expected it would stop firing once it left range like other turrets do.

Thanks for the report. It's now fixed for the next release.
