Subject: [PATCH] Cover system. Tables now give some cover from bullets and
 beams. Standing behind the table gives you 20% chance of table taking the hit
 instead. Flipped table gives +20%, but only if bullet comes from the side it
 faces. Otherwise no cover is provided at all. Lying on the floor gives +20%.

Table takes half of damage human would, and breaks down after its health goes to zero.
Reinforced talbes have double the health, wooden ones - half.
