Spawn $EDITOR to update an association list for CLI scripts.

[procedure] (edit-properties alist)

Formats alist to a temporary file and spawns $EDITOR on it (or "vi" if $EDITOR is not set).

If the editor exits with a zero error level, the file is parsed back into a new association list having keywords for keys and returned.

If the editor exits with a non-zero error, edit-properties returns #f.
