KMail: Menu options to toggle "Show Message Structure"

Subtly different from the same feature in KDE:
KDE's menu items toggle the default behaviour between always/never, and the menu item is disabled if smart is set.
For Trinity, the option is always available, and only toggles visibility of the structure for the current session.
