Fixed ignored first row of data bug; added "Logged in as XXX"

2 changes:
- Before, we were ignoring the first row of data when creating pie, bar, and line graphs in Reportal.  Now the first row of data is included.
- Added "Logged in as XXX" to the Reportal menu bar.  Also refactored the code a bit, creating a new reportalnavigation.vm file.
