Allows you to drag & drop windows files in the bash

• copy to /usr/local/bin
• make it executable (chmod a+x)
• use it for example like this ls "$(w2lp 'drag&drop windows file')"

@larsonmars: A dedicated GitHub repository with Makefile / packaging would be awesome 👍

I thought it is too simple to be worthy a repository, but if you think it's worth, I can see what I can do. Note that I just more or less followed the msdn blog to build it using visual studio, specifically targeting WSL, which was really easy.
