0dc4f9c62b hacky bugfix: support floats in nth 
Needed because we don't yet have a primitive in the shell to truncate/round
non-integers to integers.

Before:
  (nth (/ 31 10)    # we don't have float literals yet
       '(1 2 3 4))
  => NULL

..with an unpleasant abort likely later on.

Really the correct thing to do is ensure none of my primitives ever returns
NULL. Start with car/cdr.

0b3d456f2c clean up a large memory leak 
It turns out (bowboard screen 128) on a real screen massively slowed down
and ran out of memory since commit e2ab1b30b1 on May 19. The culprit was
these changes, which created memory allocations for a new trace on every
recursive call.

I originally had some vague desire to isolate these calls from the user-visible
trace. That's expensive enough that I'll wait until it becomes a concern
before trying to isolate again.

74be534e2b starting to implement first macros 
Another commit, another bugfix.

Some snippets from my currently exploding todo list:

- always investigate lookup errors immediately. Beyond the root cause, they should never happen at the moment, while we aren't reclaiming memory.
  we should always return a more precise error message. Usually involving null pointer checks.

- on abort, print out stack trace
  - emit mapping of labels to addresses during survey
  - store a mapping of symbols somewhere in the code image

- stop allocating 1KB per token; expand space for tokens as needed

.limg file is first file opened with Vim.
