Allows you to set the Youtube playback speed to whatever you want
You can use the built in slider to select speeds, or you can type in whatever speed you want. You can also use it to set a new default YouTube playback speed.
Due to technical limitations of the Youtube API, speeds seem to only work reliably in the 0.01x to 16x range.
