LRDOCS-323 added kaleo email notification code snippet and snapshot

Hey Jim,

I've been in contact with Eduardo and we tweaked a couple things to make this email notification work. The URL functions properly without the refererPlid value. Also, I am using the groupId in place of the doAsGroupId value because they are equivalent in this situation regarding workflows.

I figure as long as the email notification works for this section and gives a fundamental example of how to set up a FreeMarker email notification, the user can modify things if they have different circumstances to work with.

It seems these two values (refererPlid and doAsGroupId) among a few others can no longer be referenced by the Service Context. I notified Eduardo of these problems.
