Example of evmenu list_node decorator

## Example of use of the list_node menu node decorator

from evennia.utils.evmenu import list_node

# as part of a menu node list - decorate a node with the options.
# any extra options added in the node will also be added to resulsing
# node. Example:

@list_node(all_typeclasses_list, callable_when_selecting_option)
def typeclass_node(caller, raw_input, **kwargs):
    text = "Set the prototype's Typeclass."
    return text, {}

# ... will produce this menu node in-game:

__________________________________________________________________________________________________________

Set the prototype's Typeclass.
