Readability was previously removing (was trying to actually, see next
section) invisible nodes using a pattern from `unlikelyCandidates`. This
was quite hacky and was removed during a backport of logics from
mozilla/readability. There is still a need to remove them so here we
are. We still use a pattern but specifically against the style
attribute. We also remove nodes with the attribute `hidden`.
The clean feature of tidy actually replaces inline style attributes
with css classes thus preventing readability to detect invisible nodes,
see https://github.com/htacg/tidy-html5/blob/5.6.0/src/clean.c#L1488
We therefore set clean configuration to false.

This change backports several things from mozilla/readability:
- Add child score to all ancestors instead of the first parent only
- Check 5 top candidates and try to find alternative candidates within
ancestors, this can help to find a better parent and grab more content
- Reduce patterns from `unlikelyCandidates` to the one used by Mozilla
as ours tend to remove useful nodes
- Score headers (h2 to h6) by default in addition to div, p, td and
section

A change released in tidy 5.6.0 breaks php-tidy when using
tidy_parse_string+tidy_clean_repair and wrap=0, incorrectly wrapping
every single word. Also it seems that $tidy->value should not be used to
retrieve the repaired html as far as it is undocumented and for internal
use.
We replace the call with tidy_repair_string which directly returns the
repaired string.
