0.4.1

The project's initial release. It contains the following changes on top of [email protected]:

• chjj/pty.js#137 Fixed Windows parameters program args @the-ress ed3c9da
• chjj/pty.js#173 Support launching shells from a unicode cwd on Windows @the-ress 36b5b6f
• rprichard/winpty#74 Fix not enough storage error on Windows c75c2dc

Note that v0.5.1 is a republish of 0.4.1 as I accidentally published to the latest tag and npm didn't let me unpublish.
