* Bugfix: Using std::vectors with a struct that contains Eigen objects...

* Bugfix: Using std::vectors with a struct that contains Eigen objects sometimes causes crashes depending on OS and compiler. EndEffector::ContactInfo contains several Eigen::Vector3f variables and hence in some constellations a std::vector of it caused a crash. Now a typedef is used that encapsulates the Eigen::aligned_allocator setup and this issue should be fixed.
* The grasp preshape is now handled by grasps in order to save/load the preshape data.
