Description

This pull request fixes the tap to seek feature not using the configured skip interval, I consider this a bug fix and not a feature implementation, as it is expected behaviour and this is a regression compared to what we were doing for video.js. Seeking with the keyboard arrow keys multiplies the skip interval with the playback rate, I decided not to do that for the touch controls, as shaka-player recreates the entire UI every time you call configure, so if we had to do it every time the user changed the playback rate that wouldn't be a great experience, additionally as you can see from the code snippet linked below, we didn't use the playback rate for the touch controls with video.js either.

Lines 474 to 477 in 8b66548

	touchControls: {
	seekSeconds: this.defaultSkipInterval,
	tapTimeout: 300
	}

Testing

1. Enable the mobile emulation in the dev tools
2. Then open a video (the order of these two steps is important, as shaka-player won't activate the tap to seek feature if it doesn't detect touch support)
3. Open a second window to the settings page
4. Test various default skip interval values to check that the player uses your configured value
