Automated response: Perceived spammer notifications confidence level should not be a percentile

This hotfix converts confidence level to a percent instead of a percentile in notifications (which is better for UI).

In addition, spammer requires validation notification will now only get sent if both the request was POST and interesting POST fields were present (hopefully this reduces the number of times it gets triggered; it's really only necessary when someone actually submits something)

A hotfix (a TAR of files to upload) has been uploaded to this issue. Only apply this hotfix if you absolutely need it and cannot wait until the next release of Composr (releases are more reliable and strictly tested). As of Composr version 11, the recommended way to apply a hotfix is by following the same steps as an upgrade (https://baseurl/upgrader.php, use the hotfix on the step “Transfer across new/updated files”). The upgrader will automatically skip files belonging to addons you do not have installed or that are newer on disk than in the hotfix. Otherwise, you can manually extract and replace these files (do not replace if your on-disk file is newer than the one in the hotfix). Always take backups of your site or at least files you are replacing before applying a hotfix. Not sure how to extract TAR files to your Windows computer? Try 7-zip (http://www.7-zip.org/).
