Advanced video player

[Maniload]

The video player on the page should feature various functionalities to higher the user experience. These include:

• [x] Global player (the player should keep playing while the users changes pages)
• [x] Watch list (the player should continue playing related themes which are gathered through the context of the initial play action)
  • [x] Auto-play (auto-play should be turned on and off)
  • [x] Shuffle (play the watch list in random order, see also: https://github.com/AnimeThemes/animethemes-server/issues/77)
  • [ ] Repeat (repeat playing the current theme / cycle through the watch list)
  • [x] Play all (plays all themes in the database, can be combined with shuffle to achieve a Shuffle all function)
• [ ] Hotkeys (bind certain action to keyboard keys)

If this issue gets started we can split it in more smaller issues and use this as an overview.
