* Enabled split keyboard for landscape
Enable split keyboard is available from medium-sized (720dp) phones (landscape). On smaller phones, this toggle will be hidden. No change on tablet layout behavior.

remove old lxx themes and many of the drawables only used there (still a bunch left)
(internally) rename holo themes to match test in preferences: ICS -> HoloBlue, KLP -> HoloWhite to

happens for short words following the attempts to improve #86
now the auto-correct should only happen if suggestion has already been used in this ngram context,
and should not appear again quickly after correcting back to the typed word
e.g. type "whem" and space, autocorrected tho "when"
press delete and get "whem" again
select "when" suggestion (or any other)
get " when" instead of "when"
see example with typiny "hum" and getting "him" in #86
now either it will auto-correct, but show "hum" in suggestion strip
or it will not auto-correct if "hum" has high enough score
