[ANN] better_nested_set plugin

Hi,

I’m pleased to announce that the better_nested_set plugin is released.
It ehances acts_as_nested_set, adding methods to move parts of the
tree, like:
* move_to_child_of
* move_to_right_of
* move_to_left_of
Pass them an id or an object.

Other methods added by this mixin are:
* root - root item of the tree (the one that has a nil parent;
should have left_column = 1 too)
* roots - root items, in case of multiple roots (the ones that have
a nil parent)
* level - number indicating the level, a root being level 0
* ancestors - array of all parents, with root as first item
* self_and_ancestors - array of all parents and self
* siblings - array of all siblings, that are the items sharing the
same parent and level
* self_and_siblings - array of itself and all siblings
* children_count - count of all immediate children
* children - array of all immediate childrens
* all_children - array of all children and nested children
* full_set - array of itself and all children and nested children

It’s in its very early version, though I already use it for three sites.
Some tests and helpers to print trees to come.

Suggestions, reports and comments welcomed.

`const_missing’: uninitialized constant BetterNestedSetHelper
(NameError)

I think, “ActionView::Base.send :include, BetterNestedSetHelper” should
be removed from init.rb

Sorry, I extracted this plugin from my app and didn’t included the
helper because it’s not mature enough…
Will end it and add it back asap.
