Increase MAX_SERVERS to make sure that "find best route" feature will work properly

[zalon]

During a past GetQuad, I noticed that the "find best route" feature from ezQuake wasn't working as good as it used to. While investigating I noticed that qwfwd has a hardcoded limit of 512 servers, which it can hold from the master servers.

When GetQuad was live, there was 662 active servers and when I was testing, there was 700+.

This means that you gotta be pretty lucky that the qwfwds you need, holds the ping information for the servers you need to connect to, let alone the chain feature.

#define MAX_SERVERS 512 // we will not add more than that servers to our list, just for some sanity
