Media Controller από Technomancer

A lightweight way of controlling YouTube videos without having to keep switching tabs, inspired by Brave's media menu.
Currently supports Pause/Play, Muting, Pinning, Reloading and Closing the video tab, with more features planned and also open to suggestions.

Permissions:
`theme`: To get the current browser theme colour settings to let the pop-up menu fit with the theme better.
`tabs`: To get tab URL's to find supported tabs for hooking in.
`host; "*://*.youtube.com/*"`: To be able to manipulate the code in the watch page, search for the video stream player, and simulate the Click event.
