Subject: FS#9460 - Add a tag %mv which can be used to check if the volume
 button is being pressed (e.g %?mv<yes|no> ). It will stay true after its
 released for a little over half a second (not configurable unless someone
 comes up with a nice way to add a parameter to the tag? 1s is too long and
 .5s is too short...
