Complete rewrite (#1)
A complete rewrite of the gallery plugin: * Using flexbox * Using lightweight JS for lightbox to avoid anchor links, and allow full rotation * Add slideshow as an additional field * Make many more things configurable * Better support for dirs, allow mixed paths * Translatable captions for many files using metadata files * SCSS instead of CSS Reviewed-on: #1 Co-authored-by: Max Mehl <mail@mehl.mx> Co-committed-by: Max Mehl <mail@mehl.mx>
