[0.14.19] [debian] SIGSEGV after dns lookup problems

[iostr]

Hi,

The attached log was produced by
1) Joined one multiplayer game. Ran around a bit. Left the server.
2) Tried to join another multiplayer game.
3) Factorio crashed with SIGSEGV

The log shows problems resolving host "multiplayer.factorio.com". It should be noted that the networking stack being used in this case is very non-standard, and often makes DNS lookups fail. The networking stack in this case usually resolves the DNS name on the second retry.

Suggestion: it could be investigated if Factorio could display "could not connect to server" and allow the user to continue selecting another server (or retry) instead of crashing with SIGSEGV when this situation occurs.

BTW: thanks for such an excellent game! Awesome work all Wube developers!
