View child issue attachments in parent

[Supagoat]

I'm evaluating Mantis for our use (And I think we're going to use it), and during the evaluation, one person asked if it was possible to see the attachments of child issues in the parent.

I made the modification, and have submitted it back:

This is in 1.0rc5
