WK for WaniKani

Aug 20, 2015

- A lot of visual changes and fixes. (e.g., Navigation drawer now goes over the toolbar and below the status bar, new material icons, fixed touch feedbacks, paddings...).
- Added basic notifications.
- A lot more is stored for offline now. Radicals, kanji, vocabulary, recent unlocks, and critical items are all there when you are offline!
- Fixed a startup crash that occurred when no internet connection was available.
- Code improvements.
