Introducing vibe.d!

[Sönke Ludwig]

The server is back up and I've looked at Flask's blueprints. So they 
have a more implicit approach with annotations (once D has these, it 
would be a possible extension for vibe). Right now my corresponding 
pattern looks like this:

// create a global url router
auto r = new UrlRouter

// create application specific routes
r.get("/", &showHomePage);

// let each sub-component register its routes, possibly in a sub-path
registerVibeLog(settings, router);
registerTicker(router, "/ticker");
