Title: collection tags accept html attributes as the last element of collection

But if want to use this feature right now we have to specify `label_method` and `value_method` as `:first` and `:second` since `:last` method uses by default for `value_method` and it's not good for us. Actually, we can change default behaviour to `:second` as the `value_method` but I think it can break someone's code. Any idea?
