Display of attached emails

Hi Benny,

I'm not sure what version this changed in, but MailMate used to,

1. when viewing an email with another email message attached (actual attached eml file);
   
2. would display that attached email at the end of the enclosing email; and
   
3. when displaying that attached email, would show it in a box with a coloured background.

This used to work for me with both plain text and HTML emails, but now only works for plain text emails (or if I check the preference for Prefer plain text. (Using v1.12.5 (5635))

I'm not sure if the change is intentional (couldn't see anything in the release notes), but I think the old behaviour is better as,

1. it provides visual indication that there is an attached email message; and
   
2. it allows the attached email message to be context-clicked and dealt with (open/detach/etc). With the new behaviour, context clicking doesn't bring up a menu.

A helpful alternative would be to show the attached email message as an attachment in the attachments table like any other type of file. I think this has merit even with the return of the old display behaviour as sometimes people will attached multiple long emails, and to deal with each of the attached emails, one has to manually scroll through to find the break in the blocks.

In case its not clear email display part I'm looking at, I think it is the part that is styled by the following CSS

/* Attached messages are indented and given a frame and background color */
div.bodypart[type=message][subtype=rfc822] {
  margin-left: 20px;
  padding: 5px;
  background-color: #FDF5E6;
  border: thin solid gray;
}

Cheers,
Yen
