Mop up the spaghetti

[BillyWM]

Code seriously needs to be organized into one sane player object where user can instantiate it and just hit play. Do away with the globals and other practices.

Finally revisiting this project. Refactor is in progress.

Refactor is being done as same time as new demo. Pull in refactor from separate demo repo when done.

Successfully pulling in refactored code from demo depends on at least #12 and #14 being completed in addition to those already closed.
