This renames the file containing the `Custom_Image_Header` class to conform to the coding standards.
This commit also includes:
- A new `custom-header.php` that includes the new file, for anyone that may've been including the file directly.
- Replaces references to the old filename with the new filename.

In [38887], installing themes in the Customizer was disabled for multisite installs. However, an update link continues to be displayed when a theme update is available. Clicking the link causes a JavaScript error.
This removes that update link because updates cannot actually be performed in the Customizer in this situation.

* Add missing translators comments.
* Fix placement of some translators comments.
Translators comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools.
The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translators comments.

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.

* Introduce `WP_Customize_Themes_Section::$filter_type`, which has built-in functionality for `local` and `remote` filtering. When this set to `local`, all themes are assumed to be loaded from Ajax when the section is first loaded, and subsequent searching/filtering is applied to the loaded collection of themes within the section. This is how the core "Installed" section behaves - third-party sources with limited numbers of themes may consider leveraging this implementation. When this is set to `remote`, searching and filtering always triggers a new remote query via Ajax. The core "WordPress.org" section uses this approach, as it has over 5000 themes to search.
* Refactor `filterSearch()` to accept a raw term string as input. This enables a feature filter to be used on a section where `filter_type` is `local`.
* Refactor `filter()` on a theme control to check for an array of terms. Also sort the results by the number of matches. Rather than searching for an exact match, this will now search for each word in a search distinctly, allowing things like tags to rank in search results more accurately.
* Split `loadControls()` into two functions for themes section JS: `loadThemes()` to initiate and manage an Ajax request and `loadControls()` to create theme controls based on the results of the Ajax call. If third-party sections need to change the way controls are loaded, such as by using a custom control subclass of `WP_Customize_Theme_Control`, this allows them to use the core logic for managing the Ajax call and only override the actual control-creation process.
* Introduce `customize_load_themes` filter to facilitate loading themes from third-party sources (or modifying the results of the core sections).
* Bring significant improvements to the installed themes search filter.

This commit rearranges the order of items in the menu panel, and updates the flow for creating a menu by breaking it up into steps. Additionally, more help text has been added to guide people through the process of creating a menu.

Unify the theme-browsing and theme-customization experiences by introducing a comprehensive theme browser and installer directly accessible in the customizer. Replaces the customizer theme switcher with a full-screen panel for discovering/browsing and installing themes available on WordPress.org.

Also includes an extensible framework for browsing and installing themes from other sources.

* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.

* Moves logic from `WP_Customize_Custom_CSS_Setting::update()` into a re-usable `wp_update_custom_css_post()` function, useful for future REST API endpoint, WP-CLI command, or plugin migrations.
* Renames `customize_update_custom_css_post_content_args` filter to `update_custom_css_data` and improves the naming of the parameters. Instead of passing `post_content` and `post_content_filtered` the filtered array now contains `css` and `preprocessed` respectively.
* The second context param for the `update_custom_css_data` filter is now an array of the original args passed to `wp_update_custom_css_post()` and there is now no more `$setting` arg since it isn't necessarily being called in the customizer context.

* Add `customize_value_custom_css` filter to `WP_Customize_Custom_CSS::value()` method.
* Introduce `customize_update_custom_css_post_content_args` filter in `WP_Customize_Custom_CSS::update()` method.
* Make clear that `wp_get_custom_css()` and `wp_get_custom_css` filter are specifically for obtaining the value to render/display. Eliminate use of `wp_get_custom_css()` when getting the setting value. Use the underlying `post_value` directly when `is_previewed`.
* Move anonymous functions handing JS previewing for `custom_logo`, `custom_css`, and `background` into named functions on the `wp.customize.settingPreviewHandlers` to allow plugins to override/extend preview logic.
* Update `_custom_background_cb` to always print a `style` tag wen in the customizer preview, and update background preview logic to replace existing style element instead of appending a new style to the head so that background changes don't unexpectedly override any Custom CSS in the preview's stylesheet cascade.
