Empty Dragon's Breath Bottles in brewing stands not removable via hoppers.

Not sure if this is a technicly a bug,
but it should definitly be in there. After using Dragons Breath in the Brewing stand it leaves behind an empty bottle, wich cant be removed automaticly via redstone/hoppers. This makes automating it impossible. Please add a possibilty for hoppers below the brewing stand to suck it out.(Like lava buckets in Furnaces)
