[Mac] Track language selection should be sticky

[Eric Carlson]

Choosing a text track from the menu should make that track's language the preferred caption language. Turning captions off from the menu should disable captions in videos loaded subsequently. 

OS X has system support for these settings, so changes made by DRT should not change the settings on the user's system.

Philippe, do you know what symbol I need to export for WebCore::Page::initGroup() :

./.libs/libWebCoreInternals.a(libWebCoreInternals_la-Internals.o): In function `WebCore::Internals::resetToConsistentState(WebCore::Page*)':
Internals.cpp:(.text+0x3b0c): undefined reference to `WebCore::Page::initGroup()'

You don't need to guard these with VIDEO_TRACK like in exp.in?

> LayoutTests/media/track/track-user-preferences.html:117
> +                    createTrackElements([ 'no', 'fr', 'en',]);

trailing comma

> LayoutTests/media/track/track-user-preferences.html:127
> +                    createTrackElements([ 'ru', 'jp', 'en',]);
