Option to change WASD to ZQSD

Or a more arbitrary change to set your own moving characters would be optimal if you have a not-qwerty-layout.

Rendering/display speedup suggestion

function redraw() {
  str = "\033[1;1H"
  ...

The above sends the cursor to the top-right of the terminal without clearing it.

FWIW, I like the scroll-to-redraw effect - it's kinda reminiscent of a bouncy CRT - but the above change results in much less work for old/dumb terminals like xterm, making the whole thing a lot faster ( and decreasing dizziness by 100% everywhere :D).

An overview on escape sequences can be found in man console_codes (Linux manpages-specific); a more in-depth analysis can be found in dtterm(5), an absolutely ancient doc but the most comprehensive I've yet found (test what you read everywhere before trusting it tho).

The escape sequence listed above is practically standard and I would be very gobsmacked if you ever got an incompatibility report on it.

Also - this thing is awesome and I'll definitely be studying it at some point, awk seriously FTW! :D
(And kudos for making this tidbit such an easy fix!)
