Since we're now inserting both spam and non-spam into the database, we need to differentiate between the two.  There's already a column in the table called `approval`, but it isn't being set.  I'd recommend renaming `addSuspectedSpamToDB` to `addAkismetDataToDB` and passing in another parameter that is either 'spam' or 'notspam'.  That parameter should be added to the `$db->insert` statement.
