brian c2da7c8697 o Clean up some #includes
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.

  When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
  to the SESSIONID from the environment in direct mode or the
  NGM_PPPOE_SESSIONID message in other modes.  If no SESSIONID is found,
  default to the interface index in client mode or zero in server mode.

  When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
  of the physical device (ie, the N in /dev/i4brbchN).

  This makes it easier for the RADIUS server to identify the client
  WRT accounting data etc.
