Logging user activity in db

[vulantro]

It would be nice if this lib provided a way to log user activity. I mean, this should be configured when install, and with every successful db actions it should save the place, the action, and the new and old data with the username, provided by some other libs, eg. PHP-Auth to a pre-defined table. Like: INSERT schema.table new_data:qwe old_data: rty user_id 3
