  Log Message:
  -----------
  avr/atmega: snek_file doesn't change. stdout == stderr

Reduce code size by

 1. Realizing that snek_file is always "<stdin>" on boards without a
    file system.

 2. Noting that stdout == stderr, so we can use printf instead of
    fprintf

  Log Message:
  -----------
  Allow 3 * 'a' as well as 'a' * 3

Replication of strings and lists is supposed to work with operands in
either order, so check for that and flip them around.

Add tests for string operators.
