I added a handler for the java 7 Path class

I am very interested in contributing to your project, this is the first contribution I have worked on, and while it may be a small one, it will also make a world of difference for people as they move to java 7 and nio2.  Please give me any feedback, I am willing to make changes or additional work on this, and hope to provide many contributions in the future.

Thanks,
