Refactor HInterfaceBox and SignIn page

- Cleaned up code
- Sizes are standardized
- New HCheckBox component
- Replace RememberAccount page by a checkbox on the SignIn page
- The page can now be flicked if it's not tall enough to display
  everything

- HNumberAnimation now has an overshoot property that will set the right
  easing type, overshoot and adapt the animation factor/duration.
- HImage can now be colorized
