For better debugging, we think it'd be an improvement if the testing features for the AbuseFilter could highlight, on a given abusefilter log entry, which words or conditions were matched.

Pinging @Xaosflux and @Billinghurst to follow-up as they'll probably explain better than me. Feel free to amend the title or the description. I couldn't come with anything better.
