Code review comment for lp:~widelands-dev/widelands/net-boost-asio

* Hello Notabalis: I will proceed as follows:
 * Try "normal" network games with another instance as host and vice versa
 * Try local network gaming (assuming its IPv4)
 * Find out what wrong with IPv6 on this Mac, I have seen the error code
   (I hope you log it), So i can ivestigate there.
  * Either my Firewall needs tweaking
  * Or IPv6 Broadcasting on Darvin/OSX is different
  * or what else...

* Local Broadcasting
 - Pollutes the local network with unneeded traffic
 + Allows local computers to connect not knowing the server IP
 * it should not make normal network games fail :-)
* I think the Errror after a failed connect is already adressed in some other bug/branch
  https://bugs.launchpad.net/widelands/+bug/1690649 but this was merged to trunk
  so maybe your merge fixed it.

Lest go compiling ....
