Implement CandidateView using HorizontalScrollView
This change re-implements CandidateView using HorizontalScrollView and
customized Button, so that the candidate strip can be flingable.
This change also introduces the following features.
- Highlighting candidate strip and space bar is configurable by
@bool/config_candidate_highlight_enabled.
- Candidate strip can be centered with left/right padding if
@dimen/candidate_strip_padding size is greater than 0.
- Candidate text size is configurable by @dimen/candidate_text_size.
