Beta ppp-dhcp-plugin support

- install wrap-2-2

- update software packages:
	- ppp-2.4.3-2.wpk
	- bluetooth-20060331.wpk

- change the default configuration:

a. Bluetooth LAN Access Profile enable

b. /etc/bluetooth.conf:
# beta: activate ppp dhcp plugin - ask IP address for LAP clients using DHCP
SET PPP IP 0.0.0.0/0

c. /etc/rc.d/rc.local:
# beta: disable masq for LAP clients with IP address from DHCP server
/sbin/iptables -F -t nat
# beta: enable proxyarp LAP clients with IP address from DHCP server
echo 1 > /proc/sys/net/ipv4/conf/nap/proxy_arp
echo Bluetooth LAP DHCP plugin support enabled

- NOTE: b. and c. will not be needed in the next official release, instead a simple setting is changed in the WWW interface.
