HTML, generated by some infoboxes and perhaps other places, gets
stripped in a way that merges words together that should not be
merged. Add tr, th, and td to the list of tags that should force
word separation.

Certain html tags imply a word break, but our html stripping doesn't
understand that at all. Adjust the html stripping to inject whitespace
for all block level tags (per MDN) along with the <br> element.

Using a real HTML tokenizer fixes bugs when < or > appear in attribute
values. The old implementation used delimiterReplace(), which didn't
handle this case:
> print Sanitizer::stripAllTags( '<p data-foo="a<b>c">Hello</p>' );
c">Hello
We also can't use PHP's built-in strip_tags() because it doesn't handle
<?php and <? correctly:
> print strip_tags('1<span class="<?php">2</span>3');
1
> print strip_tags('1<span class="<?">2</span>3');
1
