	To handle Segment as SegmentHandle:
	* src/AbstractCommand.cc (execute): Rewritten.
	* src/SegmentMan.h: Segment -> SegmentHandle

	Introducded HttpResponse class, HttpRequest class to improve 
code
	extensiveness and make it clear:
	* src/HttpDownloadCommand.cc: transfer encoders are now managed 
by
	HttpResponse class.
	* src/HttpRequest.h, src/HttpRequest.cc: New class.
	* src/HttpResponse.h, src/HttpResponse.cc: New class.
	* src/HttpConnection.cc: Contruction of http request were moved 
to

	* src/HttpResponseCommand.h, src/HttpResponseCommand.cc: 
Refactored.
	* src/HttpRequestCommand.cc (executeInternal): Rewritten.
	* src/HttpAuthConfig.h: New class.
	* src/Range.h: New class.
	
	To make FtpTunnel{Request, Response}Command and
	HttpProxy{Request, Response}Command derived from
	AbstractProxy{Request, Response}Command:
	* src/FtpTunnelResponseCommand.h, 
src/FtpTunnelResponseCommand.cc:
	Derived from AbstractProxyRequestCommand class.
	* src/FtpTunnelRequestCommand.h, src/FtpTunnelRequestCommand.cc:
	Derived from AbstractProxyResponseCommand class.
	* src/HttpProxyRequestCommand.h, src/HttpProxyRequestCommand.cc:
	Derived from AbstractProxyRequestCommand class.
	* src/HttpProxyResponseCommand.h, 
src/HttpProxyResponseCommand.cc:
	Derived from AbstractProxyResponseCommand class.
	* src/AbstractProxyRequestCommand.h, 
src/AbstractProxyRequestCommand.cc
	: New class.
	* src/AbstractProxyResponseCommand.h,
	src/AbstractProxyResponseCommand.cc: New class.

	To add netrc support:
	* src/Netrc.h, src/Netrc.cc: New class.
	* src/Util.h, src/Util.cc (split): New function.
	
	* src/HttpHeader.cc (getRange): Fixed so that it inspects
