Set child order about awesome_nested_set

[adamico]

This could be extremely useful, especially when using this mixin introduced in issue 12 for retrieving descendants at any node level with a single query.

Anyone want to patch the current codebase?

I am not sure if is a good idea to implement this at model level. It seems much easier to sort each children using a helper, without querying the database.

I have created a helper method sorted_nested_set_options.. Example: (sorting by category name)

<%= f.select :parent_id, sorted_nested_set_options(@category, :name) { |i| "#{'–' * i.level} #{i.name}" }) %>

I have also created a sorted_each_with_level(objects, order) method.

bluegod, that assumes we want to sort by a field that already exists, not arbitrarily.

For example, I am building a site where the client should be able to adjust the order of items in the site navigation.
