Fake walls fix + other neat tweaks, fixes and additions

• Funnier description for squirrels;

• Improved the name of waffles' leftover trash item;

• Increased the amount of shots the stun revolver can pack to 18 - it still has weaker and less robust projectiles than stun gun but the amount of spare shots should compensate for that;

• (Almost) fixed fake walls - they still reveal this when opened (it's not a real hull breach, just space parallax in place of a missing floor turf), but it doesn't affect anything and I don't know how to fix this so I figured it should be fine for now;

  

• Beer and ale bottles are now acting like all of the other booze bottles instead of being 'cans' - can be smashed over heads and don't require being opened first anymore;

• Commented out 2 redundant supply packs containing mecha circuitboards;

• Added 3 useful crates for crew to purchase and Cargo to deliver - wheelchair crate, SM shard crate and hazmat suits crate;

• Nerfed the cost of several crates containing sophisticated Engineering machinery from "SOUL-CRUSHING" to mere "very expensive";

• Can now succumb to death using "Ghost" verb when in crit;

• Suicide verb is now no longer hidden;

• Added a way to get more medical contract scanners w/o admin intervention;

• HMG gun now requires actual high-level research and expensive materials to be crafted via mechfab;

• Can now cauterize your own wounds with actual cautery;

• Fixed humans and silicons not spawning gibs upon death;

• A bunch of gibbing animation and gibs tweaks;

• New verb for ghosts to hide their own sprite.
