- globalisation of network driver functions

Browse Source 
(Replaced EthRegDev with NetRegDev)
- rewrite/cleanup of socket.inc
- started rewrite of tcp.inc 
- port numbers in application are not byte-swapped anymore
- many more fixes and changes

- TCP does not work but UDP/IP/ICMP/ARP (partly) work.. (as before)
