* Detect comment separators at the end of comments too
* Consider TemplateStyles associated with ignored templates
This unexpectedly improves a lot of cases other than T313097 too,
mostly where <br> or {{outdent}} was used within a paragraph:
splitting comments that were previously jumbled together, or restoring
content that was previously ignored for apps / notifications.

Sequential numbers aren't great because they change when an earlier
comment is archived. Parent comment/heading IDs should change less
often.
This also makes much more sense for disambiguating subsections,
e.g. a dozen identical ===Votes=== sections for a dozen proposals.

Previously, only comments could have IDs, because we only needed IDs
for replying. But we might also use them for notifications soon.
