• rewrite the tutorial main page
• make sure all tutorial are up-to-date (ie: do them with current code)
• add missing ones (which ones?)

A tutorial about the "Moving armatures of the PR2 with services (or better the Jointrajectory-Interface if we get it to work)" would be nice...

We could also mention the interactive human tutorial in the human documentation

For 1.0, slight updates to http://www.openrobots.org/morse/doc/latest/user/beginner_tutorials/tutorial.html are also required

[severin-lemaignan]

In tutorials.rst:

• make explicit list of tutorials and reconsider the category (beginner, advanced) of some of tem
• add tags when necessary
