Looks up the enumerated type nick for @value and writes it to @key,
within @settings.
It is a programmer error to give a @key that isn't contained in the
schema for @settings or is not marked as an enumerated type, or for
@value not to be a valid value for the named type.
After performing the write, accessing @key directly with
g_settings_get_string() will return the 'nick' associated with
@value.
