Sort grouping by name/slug rather than ID

[valenvb]

It would be great to be able to sort the a group (and other sortable entities) by actual name or slug, rather than just ID. This is useful for things like numeric or alphabetical lists that aren't necessarily created in the same order they represent.

For example, I have a "years" taxonomy, if I want to add a new year between two others (say 2018 is missing) then it will have a higher ID and not get sorted appropriately in the list of all years.
