Releases for Heading field

Added the text-as-heading formatter

The new formatter allows to format any string or text field (long text is not supported) as a heading with a configurable size.

Removed unnecessary code

The FormatterBase & WidgetBase already implement the ContainerFactoryPluginInterface, no need to repeat this.

No need to inject the string translations service.

It is not necessary to render translatable select option labels, the render engine does this for us.

Fixed

• Fixed rendering empty headings:
  The heading tags where added to the render array even if no heading text was set (in case of an optional field).

Improvements and bug fixes.

Changes since 1.1:

Improvements

• Tokens support now all entity types, module no longer limited to paragraphs only.
• The heading size selector is now hidden if there is only 1 size allowed.

Fixed

• #2934662 by zero2one, jnycz: Token was missing again.

This is the first stable release for Heading field module 8.x-1.x
