Reorganize globals into a more comprehensive interface

[Matt5sean3]

As the concept for an event system has been rejected, the problem remains that detection of things like button presses and data communication needs a clear, easy to learn interface.

To open discussion on this, something that should be considered is that the touch sliders are going away and getting replaced by a joystick in the hardware. Writing this reorganization with that in mind would likely save time later on and give a better interface overall.

I think on top of this we write documentation for all of the commonly used framework functions, the headers files required to use them and their usage and put them in a single README file. This document will help solve the same problem with functions as we are trying to solve with polling events. I'm willing to take this documentation on myself.
