Image galleries

[samuelpecher]

Drop-in replacement for Trix image galleries

• new ImageGalleryNode implementing ElementNode overriding selection to force a NodeSelection at all times
• new AttachmentExtension conditionally loaded when attachments are enabled
• single-image galleries are unwrapped into a plain attachment

Contrasting with Trix, selection in a gallery is always on a node, not in-between. Galleries can be split with Enter and Backspace Del behave as expected

This is exciting!

I appreciate this is draft but I tried it and found an issue, just in case you hadn't spotted it:

1. Add gallery (2 or more images)
2. Add a standalone (non-gallery) image after it
3. Save

Now when you edit this content, Lexxy merges all 3 images into one gallery. If you happened to have a paragraph of text between the gallery and the standalone image, it gets deleted.

Also noticed that when adding a gallery at the end of the editor, the cursor appears to be positioned beyond the boundary of lexxy-editor__content

Thanks for checking it out so early!

I'd have expected http://lexxy.localhost:3000/sandbox/images to have the same issue with the gallery followed by the images. This is part of wrapping the entire content with <div> when galleries are just <div>s themselves.

@zoltanhosszu fancy having a peek?

This will be a huge feature. Thanks for working on this @samuelpecher
