SSP-2665 Event Audit Function Disable-Enable, Object Count Added
Added a new ssp-config.property:  ssp_set_develop_mode_on  when set to true will enable Event Auditing functionality.  Default is false.
Added some monitoring of increasing object count (only objects with events) to ensure they are destroyed.
SSP-2675 Removed unnecessary (callback nonexistent) event from SemesterPanelViewController
