|Subject:||Allow users to retract a fact|
Metabase should allow a user to "retract" a fact, e.g. a CPAN Tester discovers a FAIL report sent was actually a problem with the smoker. I think the fact shouldn't be deleted, but I'm not sure the best way to handle it. Generally, we've wanted facts to be immutable, so we don't want to just flip a field in a fact, yet I imagine keeping a "retraction" fact and having to check that in every search might be a backend nightmare. Needs thought, but the capability is probably a "must have" sooner or later.
