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"
Merge pull request #735 from cmadjar/imaging_browser_typo_fix
