Updated reveal zone check boxes

I saw in some images from other platforms it can take up alot of space.
Made the boxed horizontal, rather than vertical.

WIP Remade reveal zone

+ darkened card area to eaisily see boundries
+ reverted back to using a window
+ window can be resized
+ removed fake title bar and "X"
+ moved all cards revealed slightly to the right, makes it easier to
drag-select from the left

Cleanup

Changed style to use cockatrice icon

Changed cast

from static_cast to qstyleoption_cast
