Purge IP addresses from abuse reports after a configurable number of days

When anyone, logged in or out, submits an abuse report, their IP address is logged for spam and abuse prevention. The IP address is stored in the database.

We would like a Scheduler task that will run daily and set IP addresses on abuse reports created more than 30 days ago to nil. The number should be configurable; 30 is only an example.

Testing

1. Submit an abuse report

2. Have a database admin look at the report and verify that it has an IP address recorded

3. Have a database admin run the task

4. Have a database admin look at the report again and verify that the IP address is nil
