i3bar: count references to blocks

This prevents blocks from being destroyed before their hotspots are destroyed,
in case it is used for a pending click event that fires between the bar
receiving a new status, which destroys the block, and the bar rendering the new
status, which destroys the hotspot; this problem can be easily produced by
scrolling on a block that immediately causes a new status to be sent, with
multiple outputs
