Display VRAM Dump

Issue Description

Verilog and Assembly simulations can dump their VRAM to a file. We want to load that file to machine.js's VRAM through a web page similar to gpu-showcase.html. The code will be similar to gpu-showcase.js.

Add support for the dump file to be in

• binary
• text (string of space-separated hex values)

New Files

1. Create a new html file in high-level/tests/ to test your JavaScript locally.
2. Create a new JavaScript file for your code in high-level/tests/.
3. Create a new web page in docs/examples/ for users to access the functionality online.

Position Fixed for #Game:active

Issue Description

Any time you press up or down while playing a game, the page scrolls. We should make it so that when you click on the game canvas, the canvas stays in frame. I believe the easiest way to do this is position fixed.

Add all styling to machine.js, along with the other #Game styling.

Two Controllers Support

Issue Description

Currently there is support for one controller in machine.js. There should be some configurable option where some games allow two controllers. Maybe add some global variable in machine.js that the game can change?
