Highlight IMAP folder when new mail is detected in Worldclient
Adjust the folder color when new mail is detected in a subscribed folder.
If the folder has no unread email, it will be normal text.
If the folder has one unread email, it will be bold.
If the folder receives a new email, it will be bold and highlighted.
When the user views the folder, the highlight will disappear, however it can stay bold if there is unread items in the folder.
Thunderbird currently has this feature, described here: http://kb.mozillazine.org/How_do_I_check_for_new_messages_in_other_folders
We will consider add this in future versions of WorldClient.
