New feature to enable fast switching between input languages for
multilingual users. Keyboard settings lets you select a bunch of
languages to switch between from the Latin IME.
Use the Globe icon to toggle between languages.
Needs more work and some layout changes in specialized keyboards.
Also added a Russian keyboard (needs some pixel TLC at the right edge).
Also, add some comments to @string/key_i.
Currently there's a possiblity where some translator misunderstand what this means.
