more changes from SF May 2014 workshop

Hi ClojureBridge SF people!

Adding on to the work that Alyssa did, here are a few more changes based on the notes I took from our workshop.  I've updated my gh-pages branch in the same way that Colin creates his static HTML pages, if I can discern correctly.

Let me know what you think.

There's one thing that I didn't do (that I had in my notes), which is to remove the section on anonymous functions.  The larger group may want to talk about that first.
