DynamicFindersWithBelongsToNames
===========================

v1.1 - 2006/07/07

This patch enhances dynamic finders to allow use of a belongs_to association
name instead of having to use the foreign key attribute directly.  For example,
these two lines are equivalent:

  posts = Post.find_all_by_author_id(author.id)
  posts = Post.find_all_by_author(author)
