Title: Mri violated scans permission

Renamed violated scans permission according to what has been discussed during the permissions meeting. Permissions are now:
violated_scans_view_allsites
violated_scans_edit (can edit MRI protocol table)

Also fixed following bug:
- new values in the MRI protocol table during edition could not be saved => corrected call to the AjaxHelper resolved this issue
