[gcompris-devel] Integration of Beth's activities

[Bruno Coudoin]

Hi,

I just integrated on our git master branch all the activities developed
by Beth during her gsoc2012.

The new activities are:
- explore_farm_animals-activity
- explore_world_animals-activity
- explore_world_music-activity
- note_names-activity
- piano_composition-activity
- play_piano-activity
- play_rhythm-activity

Of course there are improvements to do here and there but to me this is
already at the quality level of the other activities in GCompris.

Of course, you help is appreciated to test them.

Thanks a lot Beth for your hard work, I am sure the children all over
the world will appreciate.

Bruno.
