Bug 858998 - Add seperate l10n strings for top sites
Bug 888184 - Remove the canvas-based animations introduced in the workaround for bug 822345

Bug 889560 - Remove 20minutos.es from UA overrides
Bug 884517 - Change lockscreen to not collapse button area when screenreader is enabled.

Updates:
 - Conditionally remove 'triggered' class when screen reader is disabled.
 - Also deleted some obsolete 'triggered' class removal lines that followed.
Bug 884514 - Hide windows when lockscreen is active.

Changing the style of the app iframes won't work well because it will interfere with the way that audio apps work. So we need to use aria-hidden.
