Default skin: Unread messages look like read when selected

[nene]

To illustrate the problem:
Which of the messages at the following screenshot are read and which are unread?



It looks like unread messages are the first four - distinguished with bold font - but that's misleading: unread messages are actually only distinguished by the blue star at the front. Bold face on the other hand carries no useful information, because both the unread messages and selected messages are shown in bold face.

I propose the following change:
* Selected messages - distinguished only by red background;
* Unread messages - distinguished by bold font-face and blue star;
* Read messages - distinguished only by normal font-face.

This would require only the following change in mail.css:

#messagelist tr.selected td
{
 font-weight: bold; /* remove this line */
 color: #FFFFFF;
 background-color: #CC3333;
}

#messagelist tr.unfocused td
{
 font-weight: bold; /* and also remove this line */
 color: #FFFFFF;
 background-color: #929292;
}
