Subject: Added escapespecialcharacters to format.lua to escape shell special
 characters.  Reviewed all calls to io.popen and os.execute to escape special
 characters.  Fixed file uploads in openssl and ipsectools with
 viewfunctions.lua.  Tried to fix openssl renew when subject contains special
 characters, but not done yet.
