Start implementing Game

-added ecc.sh to export compile commands
-changed EntityMemoryPool to not be singleton so that each EntityManager can have its own pool
-Entities now store a reference to the EntityManager that spawned them so they get data from the right pool
-added Random.h from learncpp.com
-DrawQueue can now be used with std::sort
-Array containers have swap function
