Idea: show ban date on card box frame

Same as there is a going to leave date for each box with a group of sets...

...there could be the ban date shown:

Related to #181

I agree that would be nice, my biggest concern would be whether it would be too wide for the banned card frame. But if we can do it in a way that will hedge against that, I'm down.

Depending on the date style and level of detail (full date vs. week number for example) it could occupy quite some space indeed.

With #181 the frame would get wider as it spans over several cards.
