Failover to working server

[KingFu]

When two or more server are configured for a map and one or more of them is down or returning http errors while others are still working. AlpineQuest keeps displaying errors for the same tiles.
So I think it would be better if AlpineQuest holds an array of working servers as of having no network issues and the last http status code was 200.
When some servers fails it retries the same tiles from working ones.

Any comment?

Sorry for the delay.
It's interesting. I've to check how difficult it is to implement.
Also, I need to find after how much failed attempts a server must be ignored, because sparse errors are usual...
