Classlimits: now fixed

We talked a bit on steam about isolating the global variables into its own object and such. I began implementing an object called GameServerConfig, but then I stopped when I realized how many global variables that would need to be renamed, and also considering other global variables that aren't actually manipulated by the server directly

In this pull request, I simply updated the classlimits array from when the host options controller is initialized. A similar thing is done to other variables like caplimit and time limit, so we'll have to keep the messy global variables for now,
