I left TODOs in Suggest.java because we must pay attention to locale
when changing character's case. Filed another Bug: 4769095 to track
that.

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.

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.

keyboard layout at most.
