Tutorial on programming in python and sage

[hivert]

There is a long series of exercises on Sage Combinat queue which are used during Sage days. They should end in sage doc. Currently they need cleanup.

TODO:

1. Check that we forgot no one in the list of authors

2. Put back the link to this tutorial in the object-oriented tutorial (see tutorial on Python object and classes #8886)
