Initial attempt at tracking bonus rolls and non-loot items. Add more loot-catching patterns, and generalize them a little more. Bonus rolls are tracked by default, non-loot stuff is not. Bonus rolls don't seem to be working, but non-loot definitely is. (It may be that the patterns for bonus rolls are not actually used by the game client, or rather, that the game client does not issue those events for bonus rolls which are not your own. I have yet to win a bonus roll since implementing the code, but one person in LFR claimed to win a bonus item which simply wasn't visible to me at all. More data needed.)
