Refine our Repeat/Loop-feature ( Include popout player & Exclude ads?)

[ImprovedTube]

• [ ] dont repeat preroll ads (bug / needs an update) https://github.com/code-charity/youtube/blob/30955c9edb6bb701601b0992766dd19d4f311509/js%26css/web-accessible/www.youtube.com/player.js#L679 https://github.com/code-charity/youtube/blob/30955c9edb6bb701601b0992766dd19d4f311509/js%26css/web-accessible/www.youtube.com/player.js#L688-L690

• [ ] when the popup player is opened while repeating,
  then the following can be prepended to the popup URL: &loop=1&playlist= VIDEO-ID

• [ ] The icon can be misleading with the 1 in the middle, because elsewhere it means "only repeat once"

  • Current: M7 7h10v3l4-4-4-4v3H5v6h2V7zm10 10H7v-3l-4 4 4 4v-3h12v-6h-2v4zm-4-2V9h-1l-2 1v1h1.5v4H13z
  • Without "1" M7 7h10v3l4-4-4-4v3H5v6h2V7zm10 10H7v-3l-4 4 4 4v-3h12v-6h-2v4z
  • With "unlimited"-sign ∞ : M7 7h10v3l4-4-4-4v3H5v6h2zm10 10H7v-3l-4 4 4 4v-3h12v-6h-2v4zm-5.998-6.283C8.272 8.994 6.453 12.769 9.365 13.612 10.592 13.828 6.116 12.577 9.172 10.579 9.846 10.266 13.938 11.638 9.678 13.563 11.411 13.876 13.505 9.352 15.677 10.476 18.119 12.179 15.135 15.814 12.036 11.831 14.968 14.063 15.469 13.396 15.928 12.728 16.928 9.225 13.342 10.518 12.084 11.855z

• [x] separate the always repeat switch from the buttons (in our function & GUI), so that it works alone. ImprovedTube.alwaysRepeat = function () { if(this.storage.player_always_repeat === true)

• [ ] allow repeating by category only like music or education (implemented at our speed-watching feature only yet. but many of our features might consider such data in future)

• [ ] remember looping (once or unlimited) for each video

• [ ] allow sticky-on with rightclick (faster than finding always repeat button in our list of features) compare https://github.com/code-charity/youtube/issues/1445
