"zip.c" has two minor bugs.
	1.	'dosTime' time stamp has only 5 bits for 'seconds' field. so it requires devide by 2.
(in function 'zip_set_timedate_from_str()')
<verbatim>-   dosTime = (H<<11) + (M<<5) + S;
+   dosTime = (H<<11) + (M<<5) + (S>>1);</verbatim>

	2.	function 'baseline_zip_page()' (as 'WEBPAGE: zip') finally calls 'cgi_reply()', but it not required.
because 'cgi_reply()' calls by caller (main.c / process_one_web_page()) after this function returned.
current version try to send '.zip' file twice.
(almost http client checks 'Content-Length' header and shutdown themself first '.zip' file received.
 so this bug did not generate twice traffic.)
