A major compatibility release to update this package to support all latest ReactPHP components!

This update involves a minor BC break due to dropped support for legacy versions. We've tried hard to avoid BC breaks where possible and minimize impact otherwise. We expect that most consumers of this package will actually not be affected by any BC breaks, see below for more details.

• BC break: Remove all deprecated APIs (individual Stdin, Stdout, line etc.) (#64 and #68 by @clue)

  All of this affects only what is considered "advanced usage". If you're affected by this BC break, then it's recommended to first update to the intermediary v1.2.0 release, which provides alternatives to all deprecated APIs and then update to this version without causing a BC break.

• Feature / BC break: Consistently emit incoming "data" event with trailing newline unless stream ends without trailing newline (such as when piping). (#65 by @clue)

• Feature: Forward compatibility with upcoming Stream v1.0 and EventLoop v1.0 and avoid blocking when STDOUT buffer is full. (#68 by @clue)
