Avoid some useless computation inside the dynamical filter algorithm and try a compatibility patch for ubuntu10.04 and ubuntu12.04 librairies use

All dumping clear, 4ms running for the herdt pattern generator with dynamical filter

Still some discontinuities in theta.

Modify the way the data of the ZMPVeolicityReferencedQP class are treated
continue the implementation of the dynamical filter of Kajita2003icra

Initialy the velocity and acceleration were the CoM's. This commit moved them to the waist, which is the default free flyer.

Continue the work on Herdt online
