/**
* Originally this was supposed to intercept http calls and redirect them
* but that is not supported in webkit2 (without using the extension api)
*
* so for now we have modified our server to serve use a base url of xhttp:
*
* so all relative urls are based on that
*
* Idea is to serve the files from the file system, so no need to setup apache etc...
* This should work for the static content like css / javascript etc.. but
* will cause issues with 'dynamic' xhr files (eg. the php stuff)
*
* the idea is nicked from geary.
*
* At present this serves from ~/gitlive/**** - that probably needs more thought..
