Added simple video preview
Remove the <video> tag when you close the preview to stop the playback.
Apply the fullscreen style only to #pv-vid-video.
Added a simple audio player too (based on HTML5’s audio tag)
Pretty printing of the track duration in the bottom bar.
Disabled preloading of videos and audios because it didn’t work on iOS (the browser won’t load the file until the user doesn’t tap play).
Added Directory deletion

Delete function is now fully functional, deletes files, folder, and folders with files (recursively).

Thanks alot _h5ai team, you guys have great code :)
