add video fragment for every event in the timeline

[Haroenv]

• pre-launch
• launch
• on-orbit
• de-orbit and landing

Source videos

• landing
• landing
• decoupling from ISS
• part of launch up to attachment with ISS
• satellite deployment

Things to take in account

• 1 video per event
• mp4 format
• put it in the /src/vid/-folder with a descriptive title
• no video file larger than 50MB
• synchronise the event with the video by adding empty ... lines or countdowns to that event (only do that if you want a certain text to appear at a certain time)
