[System] Pre-populate docker volumes with config files about dashboard

[phntxx]

Hi!

If I understand this correctly there's the following two points:

• The Docker image does not pre-populate the data-directory

Currently the Docker image does not pre-populate the data-directory. I will look into this, as it sounds like a neat feature.

• Links aren't clickable

That's actually a bug that will be fixed with the next commit. The issue is that apps.json looks like this by default:

...
{
  "name": "[NAME]",
  "URL": "[URL]",
  "displayURL": "[DISPLAYURL]",
  "icon": "[ICON]"
}
...

however, the app itself expects the key to be url, not URL. Fixing with the next commit

Yes, you got the two points perfectly. Sorry, I'm not used to Github; in hindsight I should have opened them as separate issues.

For the second point, that's great, since it means I can fix it on my end by editing my .json files. Thanks again.

I think it would be great, if all files would be included with some dummy data.
Pretty much like the "data" folder here on gitlab. They should show all possible configuration options, maybe include some comments, ...

Makes the start a little easier.
