moves std::shared_ptrs to a new implementation Advantages: - you can dereference a weak_ptr directly. This will obviously segfault on a nullptr deref if it's expired. - this is useful to avoid the .lock() hell where we are 100% sure the pointer _should_ be valid. (and if it isn't, it should throw.) - weak_ptrs are still valid while the SP is being destroyed. - reasoning: while an object (e.g. CWindow) is being destroyed, its `weak_ptr self` should be accessible (the sp is still alive, and so is CWindow), but it's not because by stl it's already expired (to prevent resurrection) - this impl solves it differently. w_p is expired, but can still be dereferenced and used. Creating `s_p`s is not possible anymore, though. - this is useful in destructors and callbacks.
