Add a deck selector to Stats (#2461)

* Add a deck selector to Stats

* Windows/Linux looks more aligned with 0 top margin

* Prevent Close button from becoming default

If user navigates to deck button with shift+tab, two buttons are highlighted
on Windows/Linux.

* Tweak deck change code

- Remove unneeded initiator argument
- Use our window as the parent, so a progress window will pop up
above the correct window if required.
