audrasjb 987bf2ede8 Administration: Allow to wrap Settings sections with custom HTML content.
This changeset improves the `add_settings_section()` function to allow developers to pass extra HTML mark-up to be rendered before and after the settings section. Extra argument `$args` can now be passed to the function, and is an array that can contain the following items:

- `before_section`: HTML content to prepend to the section's HTML output. Receives the section's class name provided with the `section_class` argument via an optional `%s` placeholder. Default empty.
- `after_section`: HTML content to append to the section's HTML output. Default empty.
- `section_class`: The class name to use for the section. Used by `before_section` if a `%s` placeholder is present. Default empty.

The HTML passed using these extra arguments is escaped using `wp_kses_post()` just before rendering. This changeset also provides a set of unit tests for this new feature.
