Use std::queue and std::vector in event system

instead of old custom code from container.cpp

* Removed initialize and shutdown event manager calls from Init.cpp as they were only used to create and destroy the old HLIST globals

* Moved code from Event Manager.cpp to Event Pump.cpp as the event queue system is only used in said file.

* Removed now useless event manager.cpp and .h files

Init.cpp
