This increases the chance of hitting the correct letter when typing a word
that exists in the dictionary, rather than only correct it after the fact.
It is most effective after 2 or 3 letters of a word have been typed and gets
more accurate with more typed letters in the word.

If 2 adjacent letters have similar probabilities of occuring, then there is no
hit correction applied.

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).
