Andrea Fercia cbd6b7b5bc Accessibility: Remove title attributes from the Meta widget.
- removes the `Powered by WordPress, state-of-the-art semantic personal publishing platform.` title attribute
- removes the title attribute from the abbreviations: contrary to a common belief, title attributes on abbreviations are only available to a minority of users, see https://developer.paciellogroup.com/blog/2019/03/short-note-the-abbreviation-appreciation-society/
- changes the term `RSS` to `feed`, as `RSS` is a technical term not all users are supposed to be familiar with
- improves the `widget_meta_poweredby` filter documentation

Gary Pendergast abcbee954f Coding Standards: Fix instances of `WordPress.PHP.NoSilencedErrors.Discouraged`.
Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

See #46732.

Andrea Fercia adc7f9fe54 Accessibility: Improve the image and gallery widgets preview accessibility.
In an authoring context, the image `alt` attribute purpose is different from the one for the front end. For example, screen reader users need to know what the selected image is, even when the original `alt` value is empty.

This change introduces a new pattern for the `alt` text in an authoring context:
- uses the `alt` text if not empty
- when there's no `alt` text, informs users the image has no alternative text and provides a reference to the image filename

Also, makes the gallery media widget preview an unordered list to make screen readers announce the number of images automatically.

Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

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.

Weston Ruter bb97df7b5f Widgets: Introduce Gallery widget for displaying image galleries.
* Galleries are managed in the widget in the same way they are managed in the post editor, both using the media manager.
* Gallery widget is merged from the Core Media Widgets v0.2.0 feature plugin and it extends `WP_Widget_Media` in the same way as is done for image, audio, and video widgets.
* Model syncing logic is updated to support booleans and arrays (of integers).
* Placeholder areas in media widgets are now clickable shortcuts for selecting media.
* Image widget placeholder is updated to match gallery widget where clicking preview is shortcut for editing media.

Andrea Fercia d1948f623a Accessibility: CodeMirror editing areas minor improvements.
- properly labels all the code editor areas (Theme/Plugin, Custom HTML widget, Additional CSS), whether CodeMirror is enabled or disabled
- adds `role="textbox"` and `aria-multiline="true"` to the CodeMirror editing area to allow assistive technologies properly identify it as a textarea
- standardizes the "keyboard trap" help text across the admin and keeps it as a list for better readability
- use the Help text elements as target for `aria-describedby`, to make screen readers read out the help text when focusing the editors
- fixes the `aria-expanded` attribute usage in the Customizer "Additional CSS" help toggle
- moves focus to the CodeMirror editing area when clicking on the associated label
- in the Plugin editor screen: changes a `<big>` element to `<h2>` for better semantics and consistency with the Theme editor screen
- also, removes a few textdomain leftovers, see `better-code-editing` and `default`
