[Bro] Bro Memory Consumtion

Instead of loading each of the "logging." scripts, you could just load  
enable-ext-logging at the top.

Oh!  I think I just noticed your problem (and it's my fault!).  Remove  
dns-passive-replication.bro from your list of scripts and I think your  
memory problems will go away.  The two dns scripts need work still.  I  
may merge the two together at some point, but they don't clean up  
after themselves very well yet and they *do* cause bad memory  
consumption problems.  Sorry about that!  I really need to get all of  
the documentation written for my scripts. :)
