More nuanced kill stats

[bobucles]

There is a statistics tab that keeps track of total kills incurred over the game, but in multiplayer that isn't very useful. I'd like to suggest two things:

1) Count items in a chest as kills for the sake of destruction statistics.
2) I'd like a tab that tracks kill statistics per player.

This can help with a few things:
- When a player blows things up, they know how much they blew up
- When a player puts things in a chest and shoots it, it's immediately obvious.

Perhaps there may be more useful things to track?
