Fixed issue where validate_uniqueness_of created invalid sql when column name was a mysql reserved word
added fixtures for valuestore also for sqlite pgsql and oci
The ActiveRecord namespace doesn't follow PSR-0 conventions, so Composer's "psr-0" autoloader fails to autoload classes.

Fortunately, loading the `ActiveRecord.php` file loads the common dependencies and registers an autoloader The Old Fashioned Way, and Composer has a config option for that.
