Jsf learning path

https://issues.liferay.com/browse/LRDOCS-1340

Hey Rich,

Here's is the long awaited Liferay Faces learning path using JSF. Back when I had originally created this learning path folder, I had given it the number *06*. This will need to change since there is now a similar numbered learning path now in master. I wasn't sure what number to change it to, so I left it unchanged, for now. 

This learning path follows a similar path as the MVC learning path, ending after creating action buttons. 

I saved the final example JSF Guestbook portlet in the learning SDK. 

Thanks!
