Option to change names

Hey,

I want to know if it's possible to add the feature to change the names of the animals/items for the chat messages.

For example for the message: you earn 10$ for killing 'bear' 
So I want the option to change the "bear" name and to make it even in my language.

I also have a question, I used the GatherRewards from umod, this plugin it's the same when you kill a player so it calls the player just 'player' instead of his username?

Thanks!
