Use stock icon instead of hardcoded icon

[Marcelo Fernandez]

If the user doesn't have the Tango icon set, this will fail:

self.icon.set_from_file('/usr/share/icons/Tango/16x16/devices/drive-removable-media.png')

(Line 137).

So, is desirable to use the GTK stock icon system; this line gets it:

self.icon.set_from_stock(gtk.STOCK_HARDDISK)

Cheers!

Besides, using the stock icon set, the current icon set (selected by the user) will be used to display the tray icon. :-)
