Add option to return instantly on single item in cli_select_item() 

cli_select_item() allows to quickly launch a menu from code, but if only
a single item is given a selection is not necessary in most cases.
Therefore we now instantly return the given value in these cases. This
can be turned off by setting return_single=False
