fixed bug in the way order_by was being used in the get_changes method
fixed way data was being checked in a test
now enabling quote_names in DBIx::Class::Storage to ensure any reserved
words that may be used by the Audit Log schema structure are not
conflicting

Note: this is not backwards compatible, and if for some reason
quote_names won't work for a specific use case then the Audit Log will
not work
ensure that the %dbi_params structure is in the connect info before
enabling quote_names
udpated version in dist.ini
updated POD and CHANGES with quote_names info
Merge branch 'release/0.4.2'
