Improve archive section navigation

[fspaniol]

Is your feature request related to a problem? Please describe. When adding multiple archives to the archive tab of the job report, it gets a bit messy to find some specific files.

Describe the solution you'd like The file navigation should follow a "normal" approach, such as: Having folders and then, when entering them, only seeing the files within such folder. So, for example, at the root of the tab, there would be: Files at the root testresult/ archives/ etc

This would greatly increase the overall usability and task of finding specific files :)
