Title: Create tab loop

Based on the concern raised by a BBB user that tabbing past the last button on the screen (the Lock Layout button) should cause focus to loop back to the first button on screen (the Mic Settings button).

Also added accessibilityDescription property to Help button and tabIndex property to Mute/Unmute me button.
