Random session drops with Coova-Chilli 1.0.12

[wlanmac]

It was recently pointed out that some VPN software will send packets to
the default uamlogoutip (which is 1.1.1.1). You can change this setting
by putting "uamlogoutip <ip address>" in your config. To disable the
option, set the IP to 127.0.0.1.
