NF: Introduce food_eaten counter

[Debilski]

Adds a new counter gamestate["food_eaten"] and bot.food_eaten that tracks the number of food pellets eaten by a specific bot.

If there is consensus, I would also remove the deaths from the UI as they are identical to the number of kills of the other team.

Closes #911

Is this a team property or a bot property?
I'm not sure what is this useful for?

Isn't this 30 - len(bot.enemy.food)?

If it is just for display in the UI, maybe we don't need to expose it in the bot object?

In the GUI I would call it simply food instead of food eaten.

Agreed on removing deaths

It is on a per-bot level so it is a bit more accurate than 30 - len(bot.enemy.food). Not sure if it is needed but if we have bot.kills then we might as well include this.

Wait, so bot.kills is a bot-level counter, not a team-level counter? Why did we do this?

I guess we can also postpone the merging of this until we have decided whether we want to thin out the Bot attributes.
