This commit make use of a custom py_shared_ptr holder type that will hold the virtual pointers to SOFA objects (inheriting from Base). The holder also keeps an internal copy of the initial python object to avoid slicing when the latter gets deleted by python before the C++ wrapper. This commit also brings several cleanup to the overall source code of the bindings.

The object created from python needs special care to avoid being deleted by the python garbage collection mecanisme. In sofa-framework#74 and sofa-framework#75 the smart pointer mecanism was refactored. The refactoring added a py::keep_alive, in addObject but didn't in other functions. The PR fix this.
