    Uninstall script for SQL Server Database
Author:
    Philip Doxakis
Description:
	Uninstall the audit trail script.
	It removes only the triggers. The Audit table must be deleted manually.
		(It is to prevent accidental delete.)
	Optional: Add "USE [DatabaseName];" at the top of the script.
Step:
	- Remove all triggers starting with "tr_audit_"
	- Remove the database trigger "tr_database_audit"
*/
