Add support for new CPTs in oik-shortcodes

[bobbingwide]

In the new block editor Gutenberg, now released as part of WordPress 5.0, the editor now provides different types of Blocks. As blocks are developed for oik plugins we want to be able to catalogue different blocks in a similar way to shortcodes. This logic can also be used in WP-a2z, for plugins such as Jetpack, Yoast SEO and WooCommerce which already provide their own blocks.

We need to develop support for documenting and formatting Blocks, Metaboxes and Panels.

After some experimentation I've decided that a separate taxonomy is needed for Block letters.
We don't want to use Letters or API Letters.

Themes that uses letter taxonomies and display Blocks / Block examples will need updating to reflect this change in the display of the A-Z pagination.

This logic will also need updating to cater for custom taxonomy displays: block_category, block_keyword, block_classification.

We need to develop support for documenting and formatting Blocks, Metaboxes and Panels.

I didn't bother with Metaboxes and Panels. The easiest way to document these is to make a video for each block, showing its Settings and any other dialogs that may appear from the block.

It may be easier but it still takes a finite time to do this.

I'm going to close this issue.
