Literate builds - a big new thing for Jenkins

Literate builds are a new way of working with Jenkins:

• Store your job definition with your code

• Each branch has its own definition (cheap/easy branching!)

• Use Markdown as your build file format - README.md is your build config.

This is a big enhancement - which can suit many ways of working (of course this isn't changing anything - you can keep using Jenkins the way you are now!).
