Solitaire: Refactor painting logic to accomodate to-be-added widgets

Browse source 
A series of events led to this change: The goal is to add more widgets
to the Solitaire GML, such as a GUI::Statusbar. To do so without this
change, the window ends up with some black artifacts between the main
Solitaire frame and the added elements, because the GML specifies the
main widget to have fill_with_background_color=false. However, setting
that property to true results in the background color of the widget
interferring with the Solitaire frame trying to manually paint its
background green. This results in flickering and some elements in the
Solitaire frame being painted over by the main background color.

To avoid all of that behavior, this sets fill_with_background_color=true
and the Solitaire frame's background color to green in the GML. Further,
the frame now only queues a paint update on the specific Gfx::Rect areas
that need to be updated. This also means we no longer need to track if a
stack of cards is dirty, because we only trigger a paint event for dirty
stacks.
