It was unclear when the bone eyedropper could be used since it stayed active even though it would be impossible to pick something. The limitation is that an armature has to be in pose or edit mode to pick from. Since that is the case we can check in the poll function if the active object is an armature and if that armature is either in pose or edit mode.
