New Guide: After The Event: How to continue with programming

I added an updated and more general version of my guide "After The Event: How to continue with Programming". (Original: http://danielpuglisi.com/articles/2013/04/rails-girls-after-the-event-how-to-continue-with-programming)

The second commit is a numeration typo fix in the index.html file. I hope this is okay.
