Convert a value to a list using a supercharged `split()`.
If `value` is a string, it is split by `separator`. If `separator` is
`None` or empty, no attempt to split is made, and `value` is returned as
the only item in a list.
If `strip` is `True`, then the split strings will be stripped of
whitespace. If `strip` is a string, then the split strings will be
stripped of the given string.
If `include_empty` is `False`, then empty split strings will not be
included in the returned list.
If `value` is `None` an empty list is returned.
If `value` is already "listy", it is returned as-is.
If `value` is any other type, it is returned as the only item in a list.
