move some audit log messages from lams_admin to lams_common (in order for system-generated audit messages such as when users are auto-created to be used)
LDEV-1134: Removed some of the extra cautious code that was there as it can trigger a class cast exception (due to the way Hibernate loads objects). Code was originally there to catch bugs during development, but now it is just causing problems.
Added MonitorGateView class for displaying learners panel in monitor in a seperate view. Removed learners panel stuff from MonitorTabView. Fixed scrolling issue in monitor.
change 'login as' to support non LAMS-DB users by maintaining LAMS shared session (universal login module uses it to verify sysadmin role before bypassing authentication)
