banip: update 0.0.6

* support multiple WAN interfaces in iptables rules,
  set 'ban_iface' option accordingly (as space separated list)
  or use the LuCI frontend
* add new "refresh" mode while triggered by fw changes (no download)
* add required ip dependency
* fix wrong 'settype' definition for firehol1 in config
