[Bugfix] Bugfixed the generator

[cleanups] Cleanup spinner

Removed useless stuff from the spinner.

The class generator used to provide wrong values for
properties that have a default value. This bugfix
also includes the capability to restore a default
value when switching from a theme providing an
overridden value to a theme providing no value.
Before, since there were no value, the old value
from the old theme was kept.

Add Page component and update ApplicationWindow and examples gallery

Add ApplicationWindow, ui rotation handling, and update examples accordingly

We may consider renaming the component, but anyway:
ApplicationWindow includes a page stack (StackView) which handles
the pages of the application.

ApplicationWindow includes an Item handling UI rotations,
and offers allowedOrientations (and other useful properties)
to help the dev handle rotation locking.

[livecoding] Add LiveCoding arena to examples gallery
