Set all values that are changed compared to the initial
set of values right after loading a new component.
This also includes a small change to the printerdemo,
so that it exposes more data to the business logic,
so that we have something to demonstrate;-)
Previously, the dark mode button was especially hard to hit on
embedded devices.
The TouchArea of the SideBarIcon used for this button was much smaller
than the others. By exposing a new property on the SideBarIcon:
icon-colorize, we can customize the colorize behaviour of the Image,
as well as the source. This allows us to re-use the internal Image for
the dark mode button. This allows us to use the default width, height
and x position of the icon. The touch areas of the sidebar buttons are
now uniform.
