Renamed Jhttpsrv to Main.  Created a different Jhttpsrv class.
Moved handlers to their own package.
Implemented HelloWorldRequestHandler.
Added MockSocket.
Jhttpsrv.handle()
Refactor GETRequestChrome.EntireMessage -> ENTIRE_MESSAGE
Jhttpsrv.run()
Added Header.getContentLength()
BugFix: In RequestParser.parseInputStream(), check for the presence of a Content-Length header field.
	Use this to decide if we read the InputStream for a body, or if we stop reading.
The main class is now Main, not Jhttpsrv.
Make sure we close the socket after we handle it.
The Main class and main method.
Version update.
