Two quickly made script files to show the IP and MAC address information.

ShowIPMAC:
 A fancy script which tries to dig the accurate info of the enabled
 interface. Shows the result in a requester window with auto close.

ShowNetStatInterfaces:
 A dumb script which just outputs the Interface information from the
 NetStat program and closes the output shell window after a while.

Both scripts can be used in WBStartup drawer, because they'll wait
until the network is up.
