In practice names are not often used so typically whenever you want to make a
window settings persistent you also need to set its name and the it's
convenient to let a single function do both tasks, so add an overload taking
the name string (this is a separate function instead of optional parameter to
avoid compilation errors if this is ever used with non-wxWindow-derived
objects which don't have SetName() method).
Also expand the documentation slightly and add @since tags.
