Enable $TriggerObject for Custom Object Updates

It would be extremely useful to be able to utilize $TriggerObject in Email Script Tokens for the "<Custom Object Name> is Updated" trigger, in addition to the "Added to Opportunity", "Opportunity is Updated", and "Added to <Custom Object Name>"  triggers.

This would provide the following benefits:

• Increased flexibility in Email sends using VTL tokens
• Increased efficiency in API use
• Increased scope of Custom Object use
