audrasjb 30a77d5fa4 i18n: Define List item separator as a WP_Locale property.
The list item separator is a locale property, and it doesn't make much sense to translate it separately in multiple projects. This changeset implements the following modifications:

- Define list item separator as a new WP_Locale property
- Add `wp_get_list_item_separator()` as a wrapper for `WP_Locale::get_list_item_separator`
- Replace `$wp_locale->get_list_item_separator()` calls with `wp_get_list_item_separator()`
- Added a compatibility layer for bundled themes

desrosj 88cedeac5c Bundled Themes: Revert the [51372] update to block patterns in bundled themes.
Upon further examination, this change was not great for backwards compatibility, resulting in block validation errors when running on older versions of WordPress.

While there are currently many `console.info()` notices caused by older format block syntax being updated to the current version included in WordPress 5.8, the blocks do not break.

Block patterns do not currently have a versioning mechanism, or a means to indicate which versions of WordPress are supported.

See #53617.

desrosj b16abdec23 Bundled Themes: Update block patterns to match the latest versions of `core/*` blocks.
When using the post editor with a bundled theme active, there will be a number of `console.info` notices printed to the browser’s console.

These notices are caused by block patterns containing outdated and deprecated versions of `core/*` blocks. Before rendering the blocks, they need to be updated, and this process outputs information to the console.

This commit also includes:

* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

Joe McGill e2b7762e9a Twenty Seventeen: Better handling of custom headers when no image is set.
This ensures that a standard header is shown on the front page whenever
a header video is set without a header image if the video doesn't load,
e.g., on mobile sizes or if the JS doesn't fire.

This adds a new class, `.has-header-video` that is added whenever the
`wp-custom-header-video-loaded` event is fired, which is then used to style
the custom headers along with `.has-header-image` whenever a header image
is available. This also changes the class name on the custom header media
wrapping `div` from `.custom-header-image` to `.custom-header-media`.

David A. Kennedy d21272ae29 Twenty Seventeen: Allow child themes to easily extend custom color patterns
By adding a filter, child themes can add additional selectors onto the custom color scheme CSS. Like so:

{{{
// Add child theme selectors for color schemes.
function dynamic_seventeen_custom_colors_css( $css, $hue, $saturation ) {
	$css .= '
	.colors-custom .content-menu > article:not(.has-post-thumbnail),
	.colors-custom .content-menu > section:not(.has-post-thumbnail) {
		border-top-color: hsl( ' . $hue . ', ' . $saturation . ', 87% ); /* base: #ddd; */
	}';
	return $css;
}
add_filter( 'twentyseventeen_custom_colors_css', 'dynamic_seventeen_custom_colors_css', 10, 3 );
}}}

Props celloexpressions.
