Update v0.5.3: Daily Reward & New PvE Challenges

Hey Everyone, This update focuses on improving the new player experience and introducing new PvE content. [list] [*] Added new tutorials in the menu when accessing the Play, Collection and Deck Edit sections for the first time [*] Added a daily reward on log in. Each day you log in you will get a predefined reward. [*] Renamed Events into Challenges. Added three new challenges, two of which will change each week. [*] Rookie Challenge - This is a one off challenge intended to allow new players a slower ramp time before they jump into ranked. [*] Weekly Challenge - This one is similar to the playoff event. Each week a new set of teams will be in the challenge. [*] Boss Challenge - These are extremely difficult challenges that offer a single opponent and will change each week. [*] Reworked the back-end purchase flow to make it more resilient and better treat some purchase edge cases. [/list] Thank you and good luck!
