Subject: [Feature] add a new org-attach dispatcher command to offline save web page

I attached the patch.

I think this feature will be helpful for use who archive web page data usually
like me. To be more portable, I also added an defcustom option for other
external command. And use an if condition to detect whether external command
available, else warning user.
