SkeletonHelper static properties are not copied in generated models

[Alzathar]

Internally the method ma::body::SkeletonHelper::reconstruct copies object dynamic properties to the generated models. However, there is no equivalent for the static properties. In some case, some of the static properties are useful for the models. This is the case for the static property sex defined in ma::body::LyonWholeBodyModel. This property is needed by some BSiP generator. Before commit 6be2a8f it was not possible to use together the LBWM model and the Dumas-McConville-Young tables. The latter was looking for the sex property not available in the given models. As a quick fix it was decided to remove the static property. However this problem might happen again with other skeleton helper.

A rework of this part is needed. At least two propositions exist:

• Implement a way to copy static properties
• Use another mechanism than the properties to set helper configuration (i.e. calibration I/O)
