Fleshed out the world class a little more and started the first step of inheriting the sprite class of SFML for the entities
Entities and by extension players now inherit from the sprite class
Tweaked the world class to add entity addition and removal
Realized that I should actually have the code able to compile before I push it
Set rendering code to use pointers to the window rather than the window itself
Got rid of an old class I no longer need
Squared away my code before I began work on world collision handling
Fixed the bug related to the world class where memory was improperly freed, and began to try and tuck in entities so that they can fit in the world class
