Update p5-DBIx-Class-Fixtures to 1.001013.

Changes from previous:
1.001013
- fixed functionality in last release by more deeply cloning parameters, which
  prevents bad things when parameters get deleted in the wrong places.  Also
  be sure we clear state properly after a dump.

1.001012
- Added new method 'available_config_sets' which returns and caches a list of
  all the json set configs found in the 'config_dir' directory.  This was added
  to make it easier when you need to dump all the fixtures programatically.
- Added method 'dump_config_sets' to let you dump more than one set at a time
  more easily
- Added method 'dump_all_config_sets' which helps automate dumping all your
  current config sets to a directory.

1.001011
- Added an excludes resultsource option to the ->dump({all=>1,...}) feature
- Allow you to directly set a configuration via a Perl HashRef instead of a
  JSON file.  Useful for testing and when you have simple or generated configs.
- New option to force use of ->create rather than ->populate.
- Fixed a bug in the test suite that would fail on certain JSON parsers
