State of HTTP Servers in Nim

[termer]

I initially dismissed it when @exelotl mentioned it because it was threaded, 
but the ability to stream requests might make it a good choice for many things. 
I still can't use it for everything since it lacks streamed responses, but 
provided it performs well enough, it may be useful for almost everything else 
if it was added as part of a framework that could handle file uploads. I'm 
certainly interested in doing some performance testing with it when I have time.
