A big commit.
- Added styling of the app. Went for turquoise background with red buttons and seekbars.
- Also added branding to the main screen with the HIOA logo and Lars and Minimon naming.
- Added watermarking in the corner of the game to easier inform if it's a test or training.
- Added a quick check to see if there is a selected user and a selected video. Both of them are needed to play the game.
- The boxes are now in a nice circle around the face!
- fixed all of the problems with the video not looping, plus a better check to see if the video is done.
