PipeScript should extend `HttpListenerRequest`

[StartAutomating]

http listener is the backbone of how PSNode and many other high-efficiency microservers work.

In order to more cleanly separate the concern of "working the listener in PowerShell" from "Working with requests in PSNode", PipeScript should extend listener objects, starting with HttpListenerRequest.

In order to be friendly to developers from other ecosystems, some of these overrides should emulate some facets of various other web requests, such as:

• express request,
• Python Http Server
• HttpRequest (aka ASP.NET class)

As there is a substantial overlap in these technologies names (since they are all variations on the HTTP standards), this will consist of a small number of methods/properties, and a larger number of aliases.

Last but not least, there should also be extensions that simplify everyday PowerShell / PipeScript Interaction with requests:
