Show custom post types in REST

[undemian]

Allow custom post types to be available in the block editor via REST api, this should complement the nice work from ​https://bbpress.trac.wordpress.org/ticket/3487 to make it easier for bbPress to support block themes and full site editing.

I couldn't apply the patch directly, I couldn't figure out why it was rejecting.

Since I couldn't get the previous patch to work, I wrote the same code again and created this patch. Now bbPress forum, topic and reply can be edited using Gutenberg block

I have tested the changes he made and Forum, Topic, and Reply are editable using Gutenberg editor. It is a good enhancement.

I would argue that this should be optional, so the following filter allows this without affecting the core plugin

<?php
add_filter ('bbp_register_forum_post_type', 'rew_gutenberg_editor') ;
add_filter ('bbp_register_topic_post_type', 'rew_gutenberg_editor') ;
add_filter ('bbp_register_reply_post_type', 'rew_gutenberg_editor') ;


function rew_gutenberg_editor ($settings) {
        $settings['show_in_rest'] = true ;
        return $settings ;
}

Lots of plugins add stuff to the custom post type pages which affects how these metaboxes display, and at best makes them look odd.

But it could be argued that it should be in, with the filter allowing opt-out.

The blocks everywhere plugin adds Gutenberg to the front end, but personally I'd not inflict ugly blocks on users who have no idea about wordpress

Branch restored. PR re-opened. This was accidental.
This PR doesn't need to be rebased to trunk, that'll be done by the committer.
