CRIT: Line drawing characters for T200 version

[hackerb9]

If you hold down GRPH + SHIFT and type

• UIO
• JKL
• M<>

you'll see line drawing characters you can use to draw the grid for the game in Tandy 200 mode.

I'm a little wary of doing this because I've seen those characters get mangled as the file gets transmitted from emulator to Windows command line to GitHub.

(Also, I kind of like the 70s vibe that using only ASCII characters gives.)

I'll look into it.
