Gulpjs session

I noticed you had Project Automation as a potential session. I've worked with grunt, yeoman, and gulp in the past few months and I figured I'd start writing some exercises for these. I started with gulp.js because it's what I'm currently using at the moment.

My writing style isn't the best and perhaps the exercises could be harder, but I figured I'd go ahead and start this. Let me know what you think!

The exercises use an example project and by the end of the exercises the user should have constructed a `gulpfile.js` that automates the construction of a simple about me page.
