Revert to old style of showing READ messages on the Desktop App#684

The old way of showing READ messages on the desktop app involved showing a light gray bar behind the read messages – which made it easier to differentiate between READ and UNREAD emails at a glance.

The current design (even with the bold / normal font + blue dot on the left) makes it very difficult to differentiate between the READ and UNREAD messages.

Agreed. And the extra on-screen clutter makes it even harder.
