Title: Refactor collection label and value methods. Closes #732

@justinfrench I wanted to check this before it goes in, because I've deleted a reference to the `grouped_value_method` option, which, unlike `grouped_label_method`, doesn't seem to have been deprecated (454dd44c00c512509ce6b9b09ad19e72e620af34). Removing it could theoretically break backwards compatibility, but it seems to be undocumented so I would expect that it's unlikely anyone is relying on it. Thoughts?
