Log Message:
Update ruby-activerecord32 to 3.2.7.

## Rails 3.2.7 (unreleased) ##

*   `:finder_sql` and `:counter_sql` options on collection associations
    are deprecated. Please transition to using scopes.

    *Jon Leighton*

*   `:insert_sql` and `:delete_sql` options on `has_and_belongs_to_many`
    associations are deprecated. Please transition to using `has_many
    :through`

    *Jon Leighton*

*   `composed_of` has been deprecated. You'll have to write your own accessor
    and mutator methods if you'd like to use value objects to represent some
    portion of your models.

    *Steve Klabnik*

*   `update_attribute` has been deprecated. Use `update_column` if
    you want to bypass mass-assignment protection, validations, callbacks,
    and touching of updated_at. Otherwise please use `update_attributes`.
