Fix https urls

The forensic interface does not work out of the box and Google Chrome shows some errors:

I updated some URLs to https. The mixed content warnings are difficult to fix. One can also ignore the problems in the browser with one click so this is no blocker. To solve the mixed content warnings I guess we need to do the following:

• Foreach resource loaded via http we should check if there is a https version available. If yes we can update the resource url and the problem is fixed.
• If not we need to download the resource to the forensic interface and serve the resource from there via https and change the resource urls then. The resources itself load other resources also which needed to be added to the forensic interface.

Since this is no blocker I will not work on this task for now.
