Bug 1033917 - [Rocketbar][RTL] Vertical Homescreen E.me search input should be right aligned in RTL locales +autoland

This patch:
Fixes Homescreen rochetbar search RTL layout.
Fixes Rocketbar clicked state of the search RTL layout.
Fixes browser chrome controls.
Fixes the issue of browser chrome progress bar.
Fixes Rocketbar problem of being initiated from the left corner of the status bar even when in RTL.
Init generally implies initialization, I don't really like the idea of a ```start()``` function calling ```init()```.

If we absolutely need a function here, can we call this something else? ```proto.animate``` perhaps?
