0.3.1

Added

• futhark-bench now tries to align benchmark results for better
  legibility.

Fixed

• futhark-test: now handles CRLF linebreaks correctly (#471).

• A record field can be projected from an array index expression (#473).

• Futhark will now never automatically pick Apple's CPU device for
  OpenCL, as it is rather broken. You can still select it
  manually (#475).

• Fixes to set_bit functions in the math module (#476).
