Everytime a Command Prompt by Pandoc pops up on Windows

[robinrosenstock]

Everytime when sublimetext-pandoc is executed the command prompt from pandoc pops up and stays open as long as the pandoc is parsing on Windows, which is very annoying and Sublime loses focus from the text. One possible solution would be to set shell=True in the subprocess.Popen invocation.

I have wrote (months ago..) a pull requests for that: Async Version #57. So this issue can be closed.
