* Kill dhcpcd.  We now use "dhcdbd", a dbus daemon that controls dhclient.
	  This means that NetworkManager shouldn't have DHCP issues anymore.  It also
	  means you need dhcdbd, which you can get here (get the latest one):

		http://people.redhat.com/jvdias/dhcdbd/

	  Technically NetworkManager can use any DHCP daemon that uses the same DBUS
	  interface as dhcdbd.

	* Rewrite device activation to facilitate the new DHCP infrastructure and
	  future improvements.  Its now "activation request" based, ie there is a single
	  activation request composed of the device, access point, and other info which
	  follows the entire activation process.  There are 5 stages of the activation
	  process which correspond to:

		1) Device preparation
		2) Device configuration (bring it up, set ESSID/Key/etc)
		3) IP Config Start (fire off DHCP if we're using it)
		4) IP Config Get (grab config from DHCP or static config files)
		5) IP Config Commit (set device's IP address, DNS, etc)

	  Note that there is no longer a "scanning" step, since the access point must
	  be known _before_ activation starts.  If the access point drops out or does
	  not exist for some reason, the entire activation process fails and must be
	  restarted for a different access point or device.

	Patch from Bill Moss:
	* gnome/applet/applet.c
		- Fix type of vpn_failure dialog -> vpn_banner dialog
