Update Yggdrasil to 0.3.11

[makew0rld]

Changelog - scroll down and look at 0.3.6 and 0.3.7 changes as well.

Because the last version was 0.3.5, there should probably be some testing to make sure everything works, but it doesn't look like there have been changes that would affect us. @darkdrgn2k you might know better?

From the changelog:

• Crypto-key routing options have been renamed for clarity
  • IPv4Sources is now named IPv4LocalSubnets
  • IPv6Sources is now named IPv6LocalSubnets
  • IPv4Destinations is now named IPv4RemoteSubnets
  • IPv6Destinations is now named IPv6RemoteSubnets
  • The old option names will continue to be accepted by the configuration parser for now but may not be indefinitely

But it looks like those were not used anywhere anyway...
