[Request] New placeholder for showing last damage given.

[Andre601]

This is a suggestion from PlaceholderAPI/PlaceholderAPI#56

Idea would be to add a placeholder to show the last damage a player has given to an entity.

My idea there is to change %player_last_damage% by splitting it up into %player_last_damage_taken% for damage the player took and %player_last_damage_given% (or dealt?) that shows the last damage the player dealt to a entity.
Only issue I see is to (temporary) store the info, since it doesn't seem like there's a way the damage a player has given is stored somewhere to easy access.

This one seems dead.
