Function to sort a resource-list by its own values/uri

[cgutteridge]

It would be nice if

$new_list = $resource_list->sort()

with no paramters just used the toString() of the list items themselves.

Might be good to allow a callback comparison function to be passed in, too.

$values = array_map(array('Foo', 'forceString'), $list);
sort($values);
