[Kalev Lember <klember src gnome org>]

commit 3feb00e37cb09a29b2c9a8adc0e9a25c2615d86d
Author: Kalev Lember <kalevlember gmail com>
Date:   Mon Feb 20 21:43:10 2012 +0200

    Construct the copyright string at runtime
    
    ... making it easier to translate, so that the string wouldn't change
    each year. Also added a comment for translators.
