Add VlcPlayer engine and update docs/enums
Introduce the new VlcPlayer live engine: add Engine-VlcPlayer.md and wire VlcPlayer into documentation, enums, settings, caches, logs, publish pipeline, preprocessor symbols, properties, and runtime-dependency pages. Update references/counts from seven→eight engines, include VlcPlayer in EngineType/PropertiesType lists, allowed-engine matrices (Gif/Video), cache and AppData paths, customization/property-panel docs, and publish scripts/docs to include the new project. Documentation clarifies libVLC is bundled (no runtime prompt) and notes hardware-acceleration behavior and GIF handling. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Add wallpaper Customize screenshots and update checklist
Add new screenshot assets and embed them into documentation. Added .images/* PNGs and replaced multiple "Screenshot needed" placeholders with actual images in Customizing-Wallpaper.md, Property-Service.md, Type-Gif.md, Type-Url.md, Type-Video.md, and Type-YouTube.md. Updated README.md screenshot checklist counts and noted which screenshots were added. This brings multiple Customize / Property editor and wallpaper-type images into the wiki and updates the checklist to reflect the additions.
Fix image paths and preview filename casing
Update documentation image references to use the repository's .images folder (e.g. .images/Gif.gif, .images/Url.gif, .images/Video.gif, etc.) and correct the Home preview link to .images/Preview.png (case change). Remove the deleted .images/preview.png asset. These changes normalize image paths used across Home.md, README.md, Type-*.md, and Using-Store.md so previews point at the repo's .images assets instead of ../.screenshots paths.
