When using the sliding spacebar language switch on ICS, both
LatinIME.toggleLanguage() and
InputMethodService.onCurrentInputMethodSubtypeChanged() invoke
LatinIME.onRefreshKeyboard().  This change eliminates the first one if
it isn't necessary.

This change also cleans up the followings.
  * reuse theme Context when the keyboard theme hasn't been changed.
  * clear the Keyboard cache when theme has been switched.
  * eliminates unnecessary Context reference from LatinKeyboard and
    SlidingLocaleDrawable.
  * recycle Bitmap and reuse Canvas in KeyboardView.

Basically Croatian keyboard is QWERTZ layout with extra letters such
as č, ć, đ, ž and š.  This change just introduces Croatian keyboard
subtype and QWERTZ layout which has the extra letters as popup mini
keyboard of base letter.

It might be great if we could have dedidated table layout.

There are already both languages keyboard layout. Finnish is based on
Scandinavian layout and Hungarian is based on QWERTZ.

Previously tab key is shown only when the input type variant says that
it is web input.  In addition to that, this change also shows tab key
when the IME option includes editor action (next and/or previous)
flag.
