New developers - spaetzle and sumsum

We could convince two other people to join our efforts. Christian Fischer aka spaetzle has recently committed the new network configuration scripts for FreeWRT (fwifupdown), which will be used as default in the upcoming FreeWRT release. Clemens Helfmeier aka sumsum is porting more packages, to get FreeWRT working as a small sized mail server. Welcome on board!
