[ ] Defining global colours
Store the colors we use (defined in #8 ) in a global and central position
[ ] Using C_components for reusability
Create the component C_content_box and use this for header and content styled data, e.g. Statistics Preview and Settings
[ ] Unify the theme and colours
The Pages Home, Lobby, Lobbies, Join and Create Game should use the same colours and look as if they are in the same app
Organize the styling.
