No images/pictures for exercises in Docker demo image

[ShanSanear]

Steps to Reproduce

1. Run the Docker demo command (i.e. docker run -ti --name wger.demo --publish 8000:80 wger/demo)
2. Log in
3. Go to exercises site

Expected results: At least some exercises having images.

Actual results: Only placeholder images are present, all calls to /media end up in 404.

Just to test things out, I checked what was going on inside the container and it seems that media folder has not been copied from /home/wger/src, or Apache2 configuration was meant to be a bit different.

Quick and dirty fix for that was cp /home/wger/src/media/exercise-images /home/wger/media/ -r so appropriate change in Dockerfile would probably do the trick.

Yes, there's something broken here, I'll take a look
