Implement cpad w/ keyboard input into runtime

This is a very basic implementation of the input system for the pc port. It maps buttons on the keyboard to cpad buttons used by the game. It requires running with a display on, and inputs are recognized in the display window. By default, the following keymapping is used:

• X to Z key
• Square to X key
• Triangle to S key
• Circle to A key
• D-pad to the arrow keys
  The rest are unmapped.

There's some functions for debugging and testing this implementation. If you want to run the pc pad util functions, you need to (ml "goal_src/pc_debug/pc-pad-utils.gc") first.
You can run a placeholder button mapping util for cpad 0 on the runtime by running (pc-pad-input-start) and following the onscreen instructions. You simply press the keys you want to attach to each button. When the mapping is complete, it is saved to memory and to the config. This is implemented with an actual GOAL process! Pretty neat.
If you wish to cancel out of the button mapping util, just press Escape or run (pc-pad-input-stop). This also means you can't map any buttons to Escape.
You can check the current button mappings by running (pc-pad-show-start). This prints the button mapping to *stdout* on your left (it's too much text however and cpad 1 is cut off). (pc-pad-show-stop) will kill that process.

Graphics (& button mapping) settings are saved to a game_config folder in the project root whenever you finish the button mapping util.

good idea to make this an option

we should add support for the namco gun :)

this file is awesome, it's great to see that we can write our own GOAL code with states and rendering and have it actually work!

I'm kind of surprised we needed more than the default stack size here. I'm guessing you hit the limit when this was smaller?
