Finished Designing the HUD

-Used the final HUD mockup to finish designing the HUD on GamePage.xaml. Consumables and helpers are now accessible on the HUD
-As we create more helpers, more helper boxes will need to be added to the HUD. The template for a helper box has already been created
-Made TitleScreen.cs and OptionsScreen.cs scale according to the player's screen resolution and snap percent. OptionsScreen.cs needs a little more work on the snapping
-Added the void AddConsumableToHUD() method in Shop.cs for adding a consumable item to the HUD
-Created a general GridView XAML Style in App.xaml
-Created a GridView XAML Style for the consumables GridView in GamePage.xaml
