compatible with other Latin's.

Also tweaks some locales' keyboard layout to match with standard PC's
keyboard layout at most.

This change introduces the following features to Keyboard XML format.

 * "keyXPos" can specify the key X coordinate directly.
 * "keyXPos" can be negative. The X coordinate will be calcluated from
    the right edge of the keyboard toward left.
 * "keyWidth" can be zero to be filled up to the right side.
 * "keyWidth can be negative. The key will be filled up to both sides.
 * Spacer's horizontalGap is renamed as keyWidth, and can be inherited
   from key-style.
 * Spacer can have keyXPos attribute.

Using these syntax, all keyboard layouts have been re-written.

This change fixes a bug that prevented to choose a prediction
several times in a row because the predictions would be replaced
right away by punctuations.
Please note several things about this change:
- Recorrection is pretty much in the middle of being refactored.
  This change has no effect on recorrection itself, but may make
  existing strange behavior more obvious when moving the cursor
  for example.
- The part of this change in Recorrection.java is not used in
  master at the moment because ongoing changes on recorrection
  result in the control never landing there, but would have been
  needed in the past and may be needed in the future.
- This change may have adverse effects on performance which need
  to be evaluated. A comment in the code has also been written
  to this effect.
- This does not fix bug 4466199, only addresses a pinpoint case
  of it to help evaluating the bigram predictions feature.
