Webserver updates

[Russell Allen]

Hi guys,

I've just pushed a minor update to the Self webserver code to github.com/russellallen/self-webserver

Apart from some refactoring, the code now handles methods other than GET and HEAD, so shouldn't be as liable to failure. 

Also, more experimentally, requests to servlets are  unceremoniously killed if they haven't returned an answer in 30 seconds. Does this sound like a good idea? Should it be longer? Shorter? The aim is to stop broken processes clogging up the system.
