Merge #428: Migrate to PageStacks

c52566d qml: Swap existing SwipeViews for PageStack (jarolrod)
f0e5951 qml: Swap existing StackViews for PageStack (jarolrod)
7ba2f62 qml: declare OnboardingWizard file, reintroduce as PageStack (jarolrod)
d49b888 qml: Introduce PageStack control (jarolrod)

Pull request description:

  After fixing our sins in #427, migrating to A StackView based GUI is quite simple.

  Here we use a custom StackView control, PageStack, that has a property `vertical` used to declare if we want vertical or horizontal animations, and additionally implements the [custom animation](#422) we want.

  Closes #422
  Closes #219
