Also adds a configuration to allow the table to have it's own display
tag (defaulting to the tag if not present).

Rename scores to “cumulative” and “individual”

See merge request !5

Mainly for things we need to override.  More to come in later commits

We still need to calculate the score for sorting purposes, but we
shouldn't display the score when no one had scored it.  Similarly, even
if there are empty comments and scores in the database for a page, we
shouldn't display the row at all.

BlockLevelPass.php adds <p> tags when there are new lines, even if you
specify that you are returning straight html that it shouldn't mess with
(and have set nowiki=>true).  But!  It doesn't do that if there are
<pre> tags around the text.  And!  It uses string matching to see if
there's a <pre> tag hanging around, even if it's in the comments.

Since this text is for comments from users, it needs to be exactly as
they inputted in, without extra things being added, for when they got to
edit.

This achieves that!

    comments turned into `<p>` tags

Style ranked score table/page

See merge request !4

Wrong index check function (for associative array rather than array)
meant that pages were overwriting each other and the table only showed
one user score per page.

If there's just a comment, the RankedChoice->getChoice function throws
a warning (no actualy error) into the logs.  Doing a quick check
beforehand to make sure the choice actually exists is cleaner.

Small bug that made the scoring a little unintuitive.  Fixes
ots/clients/lfc/torque-tracker#151

ots/clients/lfc/torque-tracker#151: Scores seem to be 0–4 instead of 1–5

Unsure if this is the correct way to go about this, but, in hopes that
it is:

- Define `ext.rankedchoice.scoretable` style resource
- Include it on the RankedScore page
