OOP Improvements

Getting closer to having the code ready to move to other files, just
needs a little more cleaning.
Fully OOP

Fully independent and object oriented version of the pong engine.
Fixed rendering bug in windows.

Added propper includes and checked timings. Timings now line up between
operating systems.
Code cleanup and shuffling

Moved the object declarations into the Pong class, it now takes less
than 5 lines of code to create a pong game.
