TODO: Convert Menu Components to Smart Pointers #20

Because I have way too many raw pointer containers for this.

Decided to implement it during the gamepad menu navigation implementation.

Gigantic refactor incoming.

Templated version of custom dynamic pointer casts with potential error handling for wrong type casting:

template<typename T,typename U>
std::shared_ptr<T>DYNAMIC_POINTER_CAST(const std::shared_ptr<U>&variable){
    std::shared_ptr<T> newVariable=std::dynamic_pointer_cast<T>(variable);
    if(!newVariable)std::cout<<"Could not cast!"<<std::endl;
    return newVariable;
}

template<typename T,typename U>
std::shared_ptr<T>DYNAMIC_POINTER_CAST(const std::weak_ptr<U>&variable){
    std::shared_ptr<T> newVariable=std::dynamic_pointer_cast<T>(variable.lock());
    if(!newVariable)std::cout<<"Could not cast!"<<std::endl;
    return newVariable;
}

Resolved in pull request #30.
