* Implement MultipleChoiceBlock (squashed commits from #5592)
* Omit widget from frozen kwargs
* Rename get_callable_choices to indicate it is an internal method
* Add release notes for MultipleChoiceBlock
Currently it is possible to pass the target attribute to a button
created using ModelAdmin's ButtonHelper framework. This allows you to
generate button links like <a ... target="_blank">.
For example, if adding a new button and modeling it after the existing
edit_button code [0], you can add {'target': "_blank"} to the returned
dict and it'll get passed to the template when the button is rendered.
To be consistent with PR 4844, and to be consistent with what seems to
be the best practice ([1], [2]), we should also support passing the rel
attribute, which would allow for creation of button links like <a ...
target="_blank" rel="noopener noreferrer">.

The order of nested InlinePanels (recently formally added in 5566)
doesn't get saved properly due to some now-invalid assumptions in the JS
selector code.
Currently, Wagtail users can use the editor up/down arrows to order
InlinePanel elements that contain child InlinePanels, but these may not
be properly saved.
Before InlinePanel nesting was supported, it was a safer bet that a
child panel would only contain one hidden input named "-ORDER". With
nesting, however, a parent panel will also contain hidden inputs named
like this for its child panels. This breaks the logic used in the
ordering code.
This change modifies the logic to use the jQuery `.children()` selector
instead of `.next()`, ensuring that we reference the correct adjacent
panel item.
An easy way to test this against current master is to use the Wagtail
testapp test models that exercise this behavior:
1. `wagtail start testwagtail` to create a new project.
2. `cd testwagtail`
3. Edit testwagtail/settings/base.py to add the Wagtail test
application `'wagtail.tests.testapp'` to the list of `INSTALLED_APPS`.
For the admin to work properly with this app, you also need to add
`'wagtail.contrib.settings'` to that list and copy the definition of
`WAGTAILADMIN_RICH_TEXT_EDITORS` from wagtail/tests/settings.py.
4. `./manage.py migrate` to create your local database.
5. `./manage.py createsuperuser` to create an admin user.
6. Create a new Event Page
(http://localhost:8000/admin/pages/add/tests/eventpage/3/).
7. Fill in all required items, and then add multiple speakers under
"Speaker Lineup". For each speaker, add at least one Award. Save the
page.
8. Try using the up/down arrows to reorder the speakers (the parent
InlinePanel), and save the page.
9. Note that when the page reloads, the ordering hasn't been saved. If
you debug using the developer tools, you'll notice that this is because
the code being modified here selects the child panel items instead of
the adjacent parent panel item.
The `wagtail_urls` patterns is a catch-all list of urlpatterns, and will
prevent any patterns later in the list from being matched. The default
case when Django is in debug mode for local development is to use
`django-admin.py runserver`, and in this case the static patterns in the
example [are redundant][1]. However for anyone using a different server
for local development, this makes them work again.

Trying to compare revisions of a page that includes changes to a foreign key
field of a related model that declared a custom primary key failed with an
uncaught exception.
The root cause was ForeignObjectComparison filtering by the id field, which is
not present in models that declare a custom primary key.
The solution is simply to filter by pk instead of id, which always maps to the
primary key of the corresponding model.
Include a regression unit test.
