Adds two admin weapons and refactors wall damage code.

The Icarus is now fireable in gun form.  The point defense mode fires several lasers one after the other so that it can penetrate.  The main gun mode fires a modified meteor.  Also added an "abstract weapon" which has the projectile type settable for admin shenanigans.
Walls now lack an armor variable, which is replaced with buffed health.  Normal walls take 4 shots with a normal laser or 5 emitter bursts to destroy.  Reinforced walls now take 20 normal laser shots or 28 emitter shots.
Added some proactive runtime protection to logging for projectile impacts.  Without a valid firer, the jump button is linked to the victim.
