Read more links could not appear when the shorten limit was obtained
inside a quote that is removed in the process, removing the read
more link node. It now get the first parent that is not inside a
quote to be sure the link is displayed.
Added the test-case that helped find this bug.

It can now take into account sections, and protect them. This allows to display a read more link
after a whole section. This will be used in the website, to display the first section of blogs for
example.
Also added some options on the read more link, allowing to tune its tag, content, as well as the link.
Also improved html_sanitize, taking improvements from the trunk branch of server, waiting for the whole
trunk branch to be merged.
