[evolution] Bug 653699 - Improve mail notifications

commit 52d27cacaf5fc469c89266c49253828b9ec80124
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sun Jul 3 11:04:31 2011 -0400

    Bug 653699 - Improve mail notifications
    
    Remove the "Generate a D-Bus message" checkbox and just do it.
    
    Replaced "Show icon in notification area" and "Popup message together
    with the icon" checkboxes with a single "Show notification when a new
    message arrives" checkbox.
    
    Re-show an unacknowledged notification message when additional new
    messages arrive.
    
    Replaced the "Default" action label in notification messages with
    "Show $FOLDER_NAME" (e.g. "Show Inbox").
