Let me hide FriendFeed items from thwirl

It'd be nice to expose Friendfeed's "Hide this" feature from within thwirl. Conversations I'm not interested in tend to keep coming back when friends comment on them. I'd like to say "hide this" early on so I don't get the noise.

Thanks for the great work, thwirl's the most usable way to access Twitter and FriendFeed.
