Avoid polling for events until we're ready for a frame redraw
...
This change drastically cuts the number of times we poll for events, and
consequently drastically speeds up the number of frames we can draw
within any given span of time.
In other words, we go from "this barely moves as fast as the actual
Apple II" to "holy shit this moves so fast".

Several core changes to status, soft switches
...
Regarding soft switches, we had several we should have been listening
for on both reads and writes, but were only doing so on writes; this is
now fixed.
Regarding statuses, we were incorrectly calculating both carry and
overflow. This should now be fixed, although some quick examinations of
disassembly output suggest there is something else amiss. Debugging will
continue shortly.

Don't create a window when testing

We do this by creating the notion of a "headless" mode, and skip window
creation in SDL.

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.

This allows us to work with the pure x/y coordinate system we set when

coordinates to whatever the window size is.
