IP_Address now handle IPv4 and IPv6 transparently

Browse Source 
IP_Address changes:
- Converts to and from String transparently while handling IPv4 as IPv6
  mapped (::ffff:[IP]) address internally.
- Completely remove AddrType enum.
- Setting/Getting of ip array is now only possible through dedicated functions
  (ie. set_ipv4, get_ipv4, set_ipv6, get_ipv6)
- Add function to know if the address is a valid IPv4 (for IP implementation and enet)
