Usability improvements for games with a large deck

[AlecM33]

When a lot of custom cards have been created, the setup page becomes quite unwieldy - cards take up a lot of space, which leads to lots of scrolling and difficulty determining which roles have been added. Give this view more options:

1. Add an option to change the cards to a much more compact "list" view vs. the default gallery view (similar to Windows File Explorer).
2. Add some sort of viewable panel that displays the current list of selected roles.

Re-design largely solves this issue with the introduction of the "custom role box"
