OpenAtlas

In develop added information about the disk space used by the project (the files directory of the project to be precise), see: https://demo-dev.openatlas.eu/admin

It would be nice to adapt the bar shown below and add the project used percentage in a different color there too. At the moment it is a jQuery progress bar displaying only used/free diskspace, which of course isn't suited to show multiple segments.
I shortly looked into other options but was soon overwhelmed so I would like to hand it over to a more frontend experienced person.

Template: openatlas/templates/admin/file.html with already available size and percentage values in disk_space_info
View: function admin_index() at openatlas/views/admin.py

We can discuss this in person in case my description is too confusing ;)
