Finish map, mapper handling for keyboard events
...
We still need to revise the test code we currently have for handling
keyboard functions; I imagine some code will need to be removed.

Make vm_area_set be an inline function.
...
Gets most of the benefits of being a macro, but also gains type safety
(which macros do not have).

Use vm_area for draw_rect.
...
This simplifies and to some degree normalizes the way we reference areas
in the vm subsystem.

Switch references from SDL_Rect to vm_area
...
We still use SDL_Rect internally, but we want to abstract the use of it
in our API. The only thing the rest of the app should care about is the
vm_area struct.

Add ability to set logical size of window at any time
...
We also removed the scale field, as the screen does not expect to manage
its own logical coordinates in SDL.
Additionally, we added an xcoords and ycoords function to the screen
externs so that you don't have to "know" that screen has those as
fields.

Really basic implementation of SDL2.
...
Plus a crappy rectangle to prove that our vm screen code is working in
principle. (It will be removed shortly.)

Actually show a window.

This is also the beginning outline of how we want to abstract graphics
away in erc.

First stab at adding graphics.
...
This involves using glfw. This first commit creates a window but doesn't
do anything with it; it also just hangs until you can escape out
somehow.
