OZP-10: Migrate displaying a dashboard.

1. Fixed header tooltip bug where it wasn't being appended to the body, so it was getting cut off by the banner.
OZP-16 Added data for admin user; more code for Person eager initializaton.
OZP-648: Current user no longer stored

Instead of storing the actual Person representing the current user
in the session and the threadlocal, only their id is now stored.  This is 
because the stored domain object did not function properly once
its transaction ended
OZP-646: Organizing functional test code
OZP-646: Simple functional test now passes
Merge branch 'master' into feature/ozp-150-create-dashboard
OZP-10: do layout after stack clears to fix FF bug where taskbard items are not sized correctly
