Add back old games

[byBlurr]

There are still some games that weren't readded... These need to be written from scratch instead of using the old games from v1.

• Blackjack with Bets, Max 5 people at a table
• Snakes and Ladders, Max 4 people at a board
• Trivia, undecided on how this will work. v1 was single player...

Blackjack will have to use its own rendering as it is not a grid game.
Snakes and Ladders can use the grid rendering.
Trivia will use embeds and most likely reactions a,b,c or d.

Would most likely use its own database table
