    edit-dialog: sort the list of calendars in alphabetical order
    
    Since gcal_manager_get_sources() returns a GList of ESource received
    from the hash table, they are not sorted alphabetically. Because of
    this, edit-dialog shows the unsorted list.
    
    I added a function for sorting this GList that is case-insensitive.
