Issue 11

[ghost]

What does this PR do?

• Upgrades Material UI to V5 (latest stable version)
• Implements a Theme Provider for MUI
• Adds responsive font support, used in the menu
• Reworks navigation, so react-router-dom is now capable of doing in-site navigations (no complete page reload)
• Implements MavButton, that reacts to the current in-site navigation pathname (active buttons are disabled)
• Alters the top navigation, in mobile view a hamburger menu is shown instead of the normal nav buttons
• Implements a navigation drawer, only visible on mobile view
• Removes the limitation that bails out of rendering in mobile view
• Moves the game cards to MUI cards
• Introdices logic to break the camera view below the hand card in mobile view
