When the User dictionary service is off, LatinIME still allows to add
words to it and it crashed if the user tries to do so. This change
fixes the crash; it does not however fix the interface.

This change makes PopupMiniKeyboardView based on KeyboardView, so that
only LatinKeyboardBaseView can manage touch event and PointerTracker.

Before starting input on new TextView, we must clear the CandidateView
because it may hold the suggestion of previous TextView or even worse
the suggestions pane has been expanded and keyboard has been hidden.

To sort out the issue, main keyboard and mini keyboard have to share
the pointer trackers.

In order to prepare for that, KeyboardView needs to be refactored as
two separate classes. KeyboardView is responsible for drawing keyboard
visual. And LatinKeyboardBaseView is responsible for handling key
event and mini keyboard as well.

To keep unit test simple, instead of specifying top padding in
the constructor, make separate setter for it.

Because Key only has bottom padding, to make mini keyboard vertically
symmetric and looks nicer, we should add mini keyboard top padding
that equals to Key bottom padding (a.k.a. vertical gap).
