Tweak to colours (staggered box on GDS themed sites)

Some "GDS" colours were being overwritten by some CSS added elsewhere.

This was affecting the staggered box on Magistrates Recruitment.

This release increases the specificity of the GDS colour CSS to match that of the colour variable declarations. The two should now be in synch.

Groundwork for dark background support in blocks

This is groundwork for changes that will follow in the Quote block, and maybe elsewhere.

It adds classes which can be used to get the text/heading colour for dark backgrounds.

The new classes are not yet used, so this can be merged with no actual changes being realized.

Moved styles from MoJ Blocks to Hale

Adds in Hale-specific rules for Highlights List and Call to Action which were previously in the MoJ Blocks repo.
These were editor-specific rules, so new file for MoJ Blocks editor only styles.
These styles are in the MoJ Blocks repo for the frontend, only the backend is Hale-specific (using our hale-editor--template-default class to identify default template in the backend)

This PR also renames the old hale-template class to hale-editor, as the class only appears on the editor screen:

• hale-template--default becomes hale-editor--template-default
• hale-template--page-full-width becomes hale-editor--template-page-full-width

These classes were only introduced in PR #314 a fortnight ago.

Added a simple reminder that, if someone changes from full width template to default template (and vice-versa), a refresh is needed.

Deprecated paragraph switch

This adds:

• a deprecated section to the Customizer
• the switch for deprecated paragraph widths.
• a class to the front end and backend if deprecated paragraphs is "yes".
• nothing else - so this does nothing at all in practice, aside from enabling the switch in preparation for the following PR.
