[Xui-interest] A minimal HTTP server is now embedded in XUI 3.0

[Luan O'C. <lu...@xo...>]

New feature:

A minimal http server is now embedded at 
net.xoetrope.optional.http.XHttpServer. When customized this server will 
allow a server appplication to signal a client via a http request. By 
customizing the server with a response handler the application can then 
respond with special actions, such as a wake-up or by requesting 
updates/new data from the server.
