Stylus addon support, Fixed tray menu dpi, Fix drag and drop subs no delay option

- Fixed tray menu not scaling with DPI
- Added Stylus addon support + Handle for HandleStylusUsoInstall (Installing from uso archives)
- Fixed drag and dropped subtitles not being handled as "ExternalEmbedded" preventing delay setting
- Added zips of unpacked extensions for use in app.
