Update p5-Rose-DB-Object to 0.796.

Changes from previous:
0.796 (10.18.2011) - John Siracusa <siracusa@gmail.com>

    * Use ENGINE=InnoDB instead of TYPE=InnoDB in MySQL table creation
      statements to avoid an incompatibility with MySQL 5.5 (RT 71757)

0.795 (07.14.2011) - John Siracusa <siracusa@gmail.com>

    * The Loader now passes the Manager class name as a second argument to
      module_preamble and module_postamble subroutines to allow Manager
      classes to be distinguished from object classes.
    * Corrected a typo in the ConventionManager documentation ("objs_"
      should be "_objs")
    * Fixed a bug that caused load-on-demand columns to be loaded by
      load(with => ...) method calls.  (Reported by Marlon Bailey)

0.794 (12.30.2010) - John Siracusa <siracusa@gmail.com>

    * Handle null default values for foreign key columns in PostgreSQL
      (RT 64331)

0.793 (12.21.2010) - John Siracusa <siracusa@gmail.com>

    * Corrected skip count in t/db-object.t

0.792 (12.20.2010) - John Siracusa <siracusa@gmail.com>

    * Detect attempts to create methods whose names conflict with
      methods defined in Rose::DB::Object itself.  (Reported by
      Dave Howorth)

0.791 (10.23.2010) - John Siracusa <siracusa@gmail.com>

    * Fixed a bug that caused on_save column triggers to fire when loading.
    * More floating point rounding fixes in the test suite.

0.790 (10.17.2010) - John Siracusa <siracusa@gmail.com>

    * The auto-initialization process no longer sets column default
      values to undef when there is no default for the column.  Doing
      this was tripping up the default_exists() method.  (Reported
      by Timo Karhu)
    * Documented the behavior of the manager_args relationship attribute
      when a relationship is used as a with_objects or require_objects
      argument.
    * Fixed a bug that caused SET columns to be erroneously marked as
      modified when their accessor methods were called.
    * Fixed a bug in make_manager_methods() that left base_name undefined.
      (RT 61963, patch by Chris Malarky)
    * Improved handling of floating point and string/number conversions
      in the test suite.
