All PresenceError is a join error

We only send presence when joining, so any error is a failure to join.

Also report error text if there is any.

Closes #2
When only "not joined" message is delivered, be more helpful

As suggested in #3
Check if someone is in the room before saying the join

It seems GTalk repeatedly sends presence to the room, even when
already joined, which was causing many extra messages.
