Changeset 45654 for trunk/src/wp-admin/custom-header.php

Coding Standards: Move wp-admin/custom-header.php to wp-admin/includes/class-custom-image-header.php

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.

See #47632.
