0.1.1

Changed

• When a stack trace is larger than the specified maximum, hide items in the
  middle instead of the end.
• Documentation improvements.

Fixed

• Do not use f64::log2 to implement std.exponent and std.mantissa, which
  can be too inaccurate in some platforms.
• Errors will not show <000D> at the end of each source line when source has
  CRLF line endings.
