Boy, you have to carry that weight!

Today I've added ability for player to carry bodies of dead enemies. There are some minor bugs, but in general it already looks as expected. 

Didn't think out yet what to do, if player dies while carrying the body. I don't use ragdolls, so player will play animation but dead-enemy will just fly at the place. It looks like there will be additional synced death animation for both player and body he carrying.
