Enforce unique names 

If a player attempts to create a tree with a name which is already used,
there are 2 possible cases:
1. The other tree the player’s own. The player is asked wheather he/she/it
   wants to replace it.
2. The other tree is from another player. This is an error. The player must
   use another name.
