Bug 1043275 - Add a meta instruction to the vertical homescreen.

Does this really work?  In the system we define the non-opaque statusbar as ```opacity: 0.1;``` to match up with the search bar on the homescreen.

Would we not need to do something like ```rgba(0, 0, 0, 0.1);```? Unless we plan on overlaying the opacity layer over the theme-color.
