Title: XNAT assessment support

The changes add support for assessments. You can browse them and download their resources.
Other changes:
- tooltips in the tree view
- scans appear with their scan type instead of their label.
- exception is caught for invalid URLs. Only for experiments at the moment, it should be handled at another level later.
