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
	"Content-Range" header instead of "Range" header.
