Special case Keep Alive packets from Anti Xray
If a server enables Anti Xray, packet sending can be delayed until the chunk has been obfuscated, blocking the entire queue from going out. On a busy server, considering Anti Xray can only operate on a single thread, it is quite possible the obfuscation backlog can get quite behind resulting in a delay of sending packets. And logging in is a clear area where lots of chunks are going to be queued for obfuscation.... We should probably special case a few more than this (such as chat), but this will hopefully help the keep alive issues some people run into.
