Missing email tab in opportunity

[pombredanne]

Current behavior

The email tab is missing in opportunity

Expected behavior

The email tab should be populated with any synced email with the "Point of Contact" persons.
This would enable looking at emails in context.

This would be great but I think we'll wait for custom layouts to do it. Because we would have to hardcode/do something dirty today to implement it. Ideally users should be able to display the mail tab on any object
