Added a destruct that will restore PHP's native handling. This 'should' help with the 'unknown at unknown' error messages.
Removed old BACKWARD COMPATIBILITY setting and cleaned up comments for LDAP config
Added getEngineDB method to allow access to engineDB. Access is restricted to EngineAPI and its modules
Added getInstance() method to allot modules to get the EngineAPI instance without re-triggering instantiation as singleton() would do.
New session manager
Removed old sessionManagement.php file
