Imaging browser typo fixes:

   - "List of Log Entries" replaced by "List of Imaging Datasets found" in the main page of the Imaging browser
   - Modified NDB_Breadcrumb.class.inc so that subtest like "ViewSession" displays on the frontend as "View Session"
I checked and it does not need a /g. "finalRadiologicalReview" subtest does show up as "Final Radiological Review".
