[evolution-patches] fix for bug #42630 (UI)

[Jeffrey Stedfast <fejj ximian com>]

The "lets display a multi-envelope icon" code can't possibly work right
now because we simply don't have icons available for it, however - it
looks quite nice if we just use the parent message status as the status
icon, but let the boldness depend on either:

1. parent is unread
2. 1 or more children are unread

+	* message-list.c (ml_tree_value_at): Don't display an unread icon
+	for a parent message status if it has unread children but has been
+	read itself. Instead, show that we have unread children by just
+	making the message test bold (which it was already doing, so
+	yay... this was easy). Fixes bug #42630.
