GCompris : I got IT Files

Main features:

- A new activity in the reading section that presents a set of image,
  text and voice to children and an exercise set around them. This
  includes about 1000 images and voice in english, spanish, french,
  and gaelic-scottish.

  The images and voices comes from the Art4Apps project
  <http://www.art4apps.org>, a big thanks to them for providing a such
  useful resource.

- A rework of many text related activities to support multigraph
  languages. This is driven by a team of gaelic-scottish users.

- Added the font face use in GCompris in the skin configuration
  file. It is possible to select another font by manually changing it
  with one installed on your system. In boards/skin/babytoy/skin.xml
  change the line "<font id="gcompris/fontface" name="sans"/>" by
  "<font id="gcompris/fontface" name="ruluko"/>". Ruluko is a font
  designated to aid those learning to read:

  In the future selecting the font should be made available at the
  configuration level.
