sending of "stickers" don't show up in any form

[pseudomonas]

If a contact sends a "sticker" message on facebook, there is no notification in Pidgin that any activity has taken place (as opposed to sending an image which generates a "* Non-Displayable Attachments *" message); result is that one appears to be ignoring such messages :-/

Yeah, it is on the TODO (#9). I hope to get this done soon.
