Now also works if the "follow-up" comment is wrapped in e.g. `<small>`.

Bartosz Dziewoński e3e4ef9de4 parser: Detect comments transcluded from another page
When trying to reply to a comment that is inside a transclusion,
detect if it's transcluded from a subpage or simply wrapped in a
template, and show appropriate error messages.

Bartosz Dziewoński b4029c3c58 Fix signatureRanges overlapping for some comments
If two signatures for a single comment were near each other,
we would sometimes treat them as one huge signature.

Bartosz Dziewoński 0ca851aa92 parser: Return signature and timestamp ranges
Currently not used for anything. May be used later for editing
comments (T245225) or reformatting timestamps (T240360).

Note that a comment may have multiple signatures+timestamps,
and we return them all so that you have to deal with that.

Fix some unrelated incorrect documentation comments.

Bartosz Dziewoński e9c401e3aa Ignore LRM and RLM before timezone indicator
They are not generated by MediaWiki, but they often appear when users
sign others' unsigned comments by copy-pasting the timestamp from the
history page.

Add test config data for nlwiki, exported by running this in the
browser console:

  copy(
    JSON.stringify( { wgArticlePath, wgNamespaceIds, wgFormattedNamespaces }, null, 2 ) + '\n' +
    JSON.stringify( mw.loader.moduleRegistry['ext.discussionTools.parser'].packageExports['data.json'], null, 2 )
  );

Bartosz Dziewoński ff0386239f Only detect comments with real signatures
Consequences of this are visible in the test cases:

* (en) Tech News posts are not detected.
  Examples: "21:22, 1 July 2019 (UTC)", "21:42, 29 July 2019 (UTC)"

* (en) Comments by users who customize the timestamp are not detected.
  Examples: "10:49, 28 June 2019 (UTC)", "21:34, 14 July 2019 (UTC)"

* (en) Comments with signatures missing a username are not detected.
  This sometimes happens if a comment is accidentally signed with
  '~~~~~' (five tildes), which only inserts the timestamp.
  Examples: "17:17, 27 July 2019 (UTC)", "10:25, 29 July 2019 (UTC)"

* (pl) A lone timestamp at the beginning of a thread is not detected.
  It's not part of a post, it was added to aid automatic archiving.
  Example: "21:03, 18 paź 2018 (CET)"

Bartosz Dziewoński e5e6fdd3af Stop using native Range objects, they're too annoying
Native Range objects are automatically updated when the DOM elements
they refer to are affected (e.g. detached from the DOM, or their offset
changes because of siblings being added/removed).

This seemed harmless or maybe even slightly useful, but it turns out
it conflicts with VisualEditor, which has to wrap the entire page in a
new DOM node when it opens (and unwrap it when it closes), effectively
temporarily detaching it from the DOM, which destroys all our ranges.

Just use a plain object that stores the same data as a Range. And when
we need to use Range's API, we can simply construct a temporary one.

The loop in parser.js assumed that there was always a heading before
any comments (not counting the page title, only section headings).

Bartosz Dziewoński 30fcfec1fd parser: Merge multiple comments on one line
Even when you have multiple signatures by multiple users in one
paragraph (or list item), it's still basically a single comment.
We don't want to offer multiple buttons to reply to it.

The changed parser test cases are illustrative:
* All affected comments in the "pl" example are comments with a
  "post-scriptum", which is now more intuitively treated as part of
  the main comment.
* The first comment in the "en" example would probably have been
  better if it wasn't merged, but a weird use of the outdent template
  causes us to not be able to distinguish that the two parts of the
  comment display on separate lines.
* The last comment in the "en" example (isn't that neat?) was previously
  incorrectly treated as two comments, because there's a timestamp in
  the middle of it (the user is referring to another comment).
* Remaining affected comments in the "en" example are also comments
  with a "post-scriptum" and their treatment is clearly better now.

It also accidentally fixes some problems with modifier tests (but not
all), where previously <dl> nodes would be inserted in the middle of
<p> nodes, to reply to the comments which are now merged.

Bartosz Dziewoński da668b72d5 Identify comments by username+timestamp+seq
Possible use cases:
* Matching comments between PHP and Parsoid HTML [implemented here]
* Finding the same comment in a different revision of a page
  (e.g. while resolving an edit conflict, or to allow resuming
  composition of autosaved comments) [implemented for highlighting
  user's own posted comment only]
* Permanent links to comments [future]

The reasoning for this form of ID is:
* _Timestamp_ by itself is a nearly unique identifier, so it's a good
  thing to start with
* Users may post multiple comments in one edit (or in many edits in
  one minute), so we need the _sequential number_ to distinguish them
* _Username_ is probably not required, but it may reduce the need
  for sequential numbers, and will help with human-readability if we
  add permanent links

The ID remains stable when a new comment is added anywhere by anyone
(excepts comments within the same minute by the same user), or when a
section is renamed.

It's not always stable when a comment is moved or when an entire
section is moved or deleted (archived), but you can't have everything.
