The changes below fix a bug where after finishing a game a new, but empty round was being created.

This caused the My Stats page to not load due to there not being a deck.id.

Removed round initialzation in the /deck route.
Split the deck/:deck name into two routes: deck/:deck_name and /deck/round/:id/deck/:deck_name
/deck/:deck initializes the round_id
/deck/round/:id/deck/:deck_name plays through the game

Split the round_setup into two methods: round_setup and game_setup
round_setup initializes the round
game_setup initializes each individual card cycle
