We now display XRAY or OREHUD when either feature is enabled.
We also fix an issue where in singleplayer mode xray nodes don't get
cleaned up. (Like they do on a server) < The ABM is still needed on the
server in cases where the server crashed.
The ABM appears to be perfect only if the server crashed, else
swapnode seems to be perfect for our code.
The ABM appears to be fired at a hard coded rate so I have set the
intervals to 0 to fire instantly. (Which means nodes will be cleaned up
quickly when a crash occured)
