Change our presence package

tmeasday:presence was doing unnecessary ping calls to the server every
5 seconds instead of using the status of the DDP connection (this
could save a fair amount of traffic in case of important server load).

I guess this change also fixes #221, but since no issue reproduction
was provided, it's difficult to tell.
