A whole new UI.

This is the first full release for v4. The main feature is that I've redesigned much of the UI. It looks better (at least in my opinion) and should adapt better to different screen sizes and size changes.

• New UI.
  • UI now has two modes for portrait and landscape (or as I like to call of it, thin and wide). This should allow an optimal experience no matter the screen size (this is especially useful for the web version).
  • The UI will adapt on the fly as the screen size changes.
  • There is no Dice screen anymore, instead replaced by a popup dice selector that can be used from ANY screen.
    • On web, you can manually navigate to /dice, in which case the old dice screen can be seen and used without having to go through the setup (or signing into Google).
  • Translate, discuss, and donate buttons have been moved to settings.
• You can now choose between additive or subtractive health modes (whether health is full at 0 or your max).
  • You should be given the option to switch it when you first start the app.
• Tweaked Google Drive to help it better handle (and report) errors and to speed up loading when you first start the app.
• Fixed a plethora of bugs.
