Since we now have the latest ipw2200 module in cooker, I've made the wireless thirdparty structure require new the firmware files (ipw-2.4-*.fw).

The generic connection layer now supports selection of the protocol (auto/DHCP/static), so it will allow to merge some more steps in the drakconnect wizard (the same will be used for xDSL/POTS/Ethernet/wireless).
