Add viator-collector plugin (Hop On Hop Off front-end reskin)
Consolidate the plugin into the TourWebsite repository (its separate nested git repo has been removed). Includes the full new-design reskin: scoped design stylesheet, SVG icon sprite, rebuilt listing/single/section templates, and homepage hero/FAQ/testimonials shortcodes.
