Subject: [PATCH] New predicates, including Not (Unary), Any/All (Polyadic), and NotMatch/NotIn (Binary)

This patch adds support for some new types of predicates and
cleans up a few small things. Tests are included.

It adds a unary predicate, Not. Predicate#not will negate the predicate
on which it's called.

Autojoin sample results:

  a = Article.includes(:comments).where(:comments => {:moderations => {:value => 1},:body => 'hey'}).autojoin

  Article Load (0.4ms)  SELECT "articles".* FROM "articles" INNER JOIN "comments" ON "comments"."article_id" = "articles"."id" INNER JOIN "moderations" ON "moderations"."comment_id" = "comments"."id" WHERE (("moderations"."value" = 1 AND "comments"."body" = 'hey'))
  Comment Load (0.4ms)  SELECT "comments".* FROM "comments" WHERE ("comments".article_id = 1)

  a = Article.eager_load(:moderations).where(:comments => {:moderations => {:value => 1},:body => 'hey'}).autojoin.first

    Article Load (0.3ms)  SELECT DISTINCT "articles".id FROM "articles" LEFT OUTER JOIN "comments" ON "articles"."id" = "comments"."article_id" LEFT OUTER JOIN "moderations" ON "moderations"."comment_id" = "comments"."id" INNER JOIN "comments" "comments_articles" ON "comments_articles"."article_id" = "articles"."id" INNER JOIN "moderations" "moderations_comments" ON "moderations_comments"."comment_id"

      Check = Struct.new(:box, :label)

      # Behaves almost exactly like the select method, but instead of generating a select tag,
      # generates Checks. These consist of two attributes, +box+ and +label+,
      # which are (unsurprisingly) the HTML for the check box and the label. Called without a block,
      # this method will return an array of check boxes. Called with a block, it will yield each
      # check box to your template.
