Bundle winpty binaries with Python wheels

[andfoy]

After looking at spyder#4753, I realized that users that install pywinpty without conda might have some problems because they don't have the winpty.dll and winpty-agent.exe binaries on their path. Is it possible to distribute them inside the Wheel package? @ccordoba12

I succeed on this

you could have a look at yawinpty

and I also bundled winpty source so that everyone could build source tarball without winpty pre-installed

@titansnow why did you create another project instead of using contributing to this one?

[ghost]

because I don't know this project when I first start that one :)

when I got to know this project, my project is finished basically

@andfoy, I think you can put both the exe and dll files in the directory where pywinpty is installed (i.e. in site-packages).

Please try that and let me know how it goes.

@ccordoba12 Bundling the winpty binaries actually works, I will update the RELEASE file then, also I'll release 0.1.3

Please read the comment I left in your PR before merging it. Also, please build a wheel locally and verify that the winpty files are inside it.
