comments: Display number of comments in comment action link.

This was not doable before, but when I added transitive dependency handling
in the big dependency rewrite, it became possible to include a comment
count when inlining.

This also improves the action link when a page has no comments. It will
link direct to the cgi to allow posting the first comment. And if the page
is locked to prevent posting new comments, the link is no longer shown.
