Improve exception safety with smart pointers

[elfring]

Would you like to wrap any pointer data members with the class template “std::unique_ptr”?

Sorry for delay (many work in last months) and thanks for the feedback! Yes, this is planned in many places. For example GameObjects, which are currently passed with raw pointers, causing segmentation faults in editor code, it requires a lot of refactoring but I'l definitely do this.
