[gnome-calendar] Added actua date mark to implemented views.

[Erick PÃrez Castellanos <erickpc src gnome org>]

commit f462712227ef451d21d3a211f7ba4b79fc352efa
Author: Erick PÃrez Castellanos <erick red gmail com>
Date:   Fri Jul 13 00:17:39 2012 -0400

    Added actua date mark to implemented views.
    
    Following mockups by Reda Lazri, the actual day it's marked by drawing a box
    around the weekday and a 2px line on the cell belonging to the actual date.
    Added icon to gnome-calendar.desktop. Tweaked css a little bit.
