[Click] nsclick: runclick patch

[Michael Neufeld]

Hi-
It's been a while, but as I recall I didn't make "$ns_ run" do the 
runclick purely as an end-user control issue. I had a notion that I 
might want to delay the start of some or all nodes until some later 
point in the simulation so didn't add code to start them all 
automatically. Of course, that kind of delayed start could easily be 
accomplished with the write handlers now (not part of the first nsclick 
rev), so I don't think there's any reason not to automatically start up 
the click routers when the simulation starts.

I'd try adding the functionality by overriding the MobileNode "reset" 
method in the ClickNode subclass and calling runclick after doing 
whatever other "reset" stuff the MobileNode superclass needs to have 
done. The "reset" method on each node gets called once when first 
running the simulation, and I don't think it gets called after that. I 
should have some time to reconstitute my nsclick dev environment and 
give it a shot over the next day or two if nobody else gets to it first.
