[Feature Request] option to show parallel investigators in new deck list

[Emmental18]

When i create a new deck, i frenquently go on the "new deck" page and take a look at the investigators to make a choice. With the growing number of // investigators (like... 11 ? 12 ?), it's becoming hard to remember every one of them, and their special abilities/deckbuilding.

Suggestion : add a check box "show parallel invesgators" on the new deck page (alongside the existing "Only investigators in your collection" box. When ticked, they will appear on the page.
