Add zero check for bot spawn limits

If the spawn limit rule is set to 0 and spawn limit is set by bucket, if no class buckets are set, it defaults to the rule of 0 and renders the player unable to spawn bots.

This adds a check where if the rule and class bucket are 0, it will check for the spawn limit bucket
