Abstractify the Program.pde file

[lazarcl]

Program.pde should have virtually zero code. Lets try and remove all constants, functions, etc and put them places that make more sense.

Ex: the BUFFERSIZE constant was initially for testing but now we rely on it throughout the code. Find a way to remove this constant and use passed values.

It is currently just setup and draw. Potentially the only things left to remove is the filenames and the fonts

[lazarcl]

Should we put the filenames in some sort of config file? Seems strange to have them where they are.
