Lock piles from being viewed without owner consent

[brine]

From a facebook community post:

Is there any appetite for preventing your opponent from looking at your deck without your consent? We have a small band of players/accounts that do this on a regular basis. I am proposing making it hidden zone that can only be viewed after granting permission by the user explicitly. Thoughts?

From Discord:

I might have asked this previously, but is there a way to lock the Decks so that player A can't right-click on player B's deck and look at > all cards?

Suggested solution:

Add a protected setting to piles, configurable in the game def, in-game pile submenu, and python. 3 states: - "True", "False", "Ask"
A Protected pile cannot be viewed by non-owner players.
The "Ask" state will send a view request dialog to the owner asking to grant permission to view.

Dialog options:

• "Always" (sets the protected setting to False, pile behaves as it currently does).
• "Yes" (Grants permission to view the pile via a network call. A message is posted in chat when they stopped looking (it already does this?). If the player wants to view again, they have to send a request again).
• "No" (denies the request)
• "Never" (sets the protected setting to True, will lock the deck from access, won't prompt the dialog anymore)
