[C++][CMake] Merged fake-fcl with fcl.hpp (splitted in .hpp and .hxx file). Propagated flag -DWITH_HPP_FCL to all binaries

[C++][Python] One can contruct a GeometryModel and Data even if hpp-fcl is not found. All stuff related to collisions is not available but geometryPlacements are ( for visualisation in the viewer especially).

[CMake] Solved bug #236. Marginally changed the source/header listing policy to avoid similar bugs in the future.

Renamed JointXXAccessor to JointXX + renamed traits<D>::JointData to traits<D>::JointDataDerived, same for Model.

As it is done in src/multibody/parser/python.cpp, one can create a shared_ptr to a new Model in c++,
send this into a python namespace, update it in python, and continue to work on the Model in c++.

An example to use this as a simple parser is given in unittest/python.cpp and models/simple_model.py

(squashed version)

Eigen::ProcuctReturnType becomes Eigen::Product in Eigen version >=
3.3.0.

[Python] Rename file into joint-derived.hpp to correspond to the type it exposes. i.e it does the exposition for each derived joint model ( that are in the joint model variant

Completed the visitors on JointVariants for each method of the JointBase interface  and moved it to a different file.

[C++][Python][Major] Replaced the way collisions and visuals are stored in GeometryModel. Now it is two lists of GeometryObject (one for collisions, one for visuals) aggregating information instead of multiple vectors. Now handle multiple collisions/visuals for one link when parsing urdf file and keep track of the mesh absolute path. Changed binding accordingly.
