To log or not to log, that is the option
When you look at the logs, sometimes you get a big list of the same culprit attempting to register. This update allows you to :
1. Not have to log events (at all)
2. Not log events if the same username has already been logged by this plug-in
3. Not log events if the same email address has already been logged by this plug-in
4. Not log events if the same IP address has already been logged by this plug-in
