	* library/http2.1/http.tcl: Fixed a newly introduced bug where if
	there's a -command callback and something goes wrong, geturl threw
	an exception, called the callback, and unset the token.  I changed
	it so that it will not call the callback when throwing an
	exception (so the caller only finds out about a given error from
	one place).  Also, fixed http::ncode so that it actually gives you
	back the http return code (i.e. 200, 404, etc.) instead of the
	first digit of the version of HTTP being used (i.e. 1).
