Mini Go Web Stack

Description

This represents a proof of concept, minimal web stack. I used http://nicolasmerouze.com/build-web-framework-golang/ series of articles as a starting point and the goal was to keep the stack as minimal as possible while still being useful for practical purposes. And of course, use the standard library as much as possible and only integrate components compatible with it.
