Singleton Validations plugin

Hi --

Inspired by a question from 'mickey' on IRC (mickey, where art thou?),
I have written a plugin that lets you do class-style validations on
individual ActiveRecord objects, like this:

   t = Thing.new
   t.validates_size_of :name, :minimum => 5

and so on.

It's at
http://www.risleydale.net/svn/plugins/singleton_validations/trunk

Enjoy, and let me know if any questions or problems.

My chaining of method_missing wasn't behaving well with missing
methods of the form validates_blah, so I've fixed it and added a test.
