Change the UI of Voice IME to be more like Voice Search.

There has been a bit of refactoring in RecognitionView in particular to fix the portrait layout.

The main issues found were:

- the size of the keyboard is specified in inches, and
(cm)(inches + inches) != ((cm) inches) + ((cm) inches))

- the height of keyboard background is high as the landscape keyboard, but it higher than
the portrait keyboard. This is not an issue on LatinKeyboard, as it overwrite the
onMeasure method. However, if I use the same image background in RelativeLayout
the Relative layout height is set to the height of the background, thus higher than the keyboard

- the change configuration was not propageted correctly
