wicd: integrate with upstart events

quite some services need to be started/restarted when a connection is
established/teared down. Also, some services are optional depending on
the connected access point. For example: use a vpn on an untrusted
network.

these small trigger scripts don't change any behaviour by themselves,
but allow you to hook in to them if you need.

example use:

  jobs.gw6c.startOn = pkgs.lib.mkForce "started  openvpn-dcsOffice";
  jobs.gw6c.stopOn  = pkgs.lib.mkForce "stopping openvpn-dcsOffice";
  jobs."openvpn-dcsOffice".startOn        = pkgs.lib.mkForce "wicd-postconnect";
  jobs."openvpn-dcsOffice".stopOn         = pkgs.lib.mkForce "stopping network-interfaces or wicd-predisconnect";

In the example, I use 3 layers. When a physical connection is
available (wifi connect), I setup a vpn connection, and setup an ipv6
tunnel on top of that. When disconnecting, they are automatically shut
down in the right order as well.
