Confirm user reports in Observation tab in bulk.

Currently the only options for reports en masse are creating a rule based on the domain i.e. Do not warn anymore for user or regardless of recipient, delete the message, or do not take action. For emails the user mark as spam or greymail reported as safe, it would be easier to use the checkboxes for all of them and mark as confirmed. Spam the user doesnt want to see it anymore and safe greymail without any other threat is fine.
