    source-dialog: use case-insensitive sorting in the calendar list
    
    g_strcmp0() is used when comparing the display name of the ESource.
    This is not a valid sort, because in this case we will get an order
    like "a" < "z" < "B" < "Z", but it should be like "a", "B", "z", "Z".
    
    We will use g_ascii_strcasecmp() to fix it.
