* Make "Are you sure?" on comment reply deletion correct size
* Update wording of warning after editing comment
* Tighten up height of comment warnings
Fixes #7083. Override default FieldBlock / BoundWidget behaviour so that:
* BooleanBlock.get_form_state bypasses CheckboxInput.format_value (which Django uses to determine the 'value' HTML attribute rather than the checked state)
* BoundCheckboxInput.get_state / set_state / get_value work with the 'checked' attribute rather than 'value'
* Add warning to bottom of draft comments
* Add a warning to bottom of edited comments
* Add a warning at the bottom of comments with unsaved replies
* Set role="status" on the comment notice
Without this, any project that uses django.forms.widgets.CheckboxSelectMultiple crashes needlessly in any step that touches the database, because of Telepath's "don't know how to pack object" error.
Simply applying WidgetAdapter to CheckboxSelectMultiple seems to work fine, though I haven't tested it in any robust way. I just went in to my site that uses CheckboxSelectMultiple in several places, and confirmed that it still works.
Fixes #7070. BlockWidget now evaluates js_context / block_json lazily on first render, so that it doesn't try resolving media files on startup, which may fail if (for example) ManifestStaticFileStorage is in use and collectstatic has not yet been run.
* Version bump to start work on 2.14
* Removed StreamValue.stream_data and StreamValue.TupleView
* Rotate deprecation warning classes
* Set up changelog and release notes for 2.14
* Changelog / release note for #7023
* Add 2.14 to the compatibility table in the upgrading guide
Having a module called logging clashes with the standard library one in weird ways (specifically: it causes a circular import error when running django-admin compilemessages from inside wagtail/core)
Also remove Turkish (Turkey) from the list - it now appears as a duplicate in the list, and the usefulness of having both Turkish and Turkish (Turkey) is questionable enough that people who really want it should opt in via WAGTAILADMIN_PERMITTED_LANGUAGES
