Update landing page with draft agenda.

During today's meeting we decided to arrange the schedule around the Best Practices paper (http://arxiv.org/abs/1210.0530).  After creating the list of 10 practices, some seemed more appropriate to a boot camp than others, and the shell doesn't really exist there at all...

Day 1
* Setup help (pre-workshop) [30 min]
* (Motivation) What we know about software engineering : @stevemcgough [45 min]
* The Shell : @gonuke [60 min]
* Automating Workflows == Shell automation and Makefiles : @gonuke [90 min]
* Write Code for People == Variables and Data Structures : @stevemcgough [90 min]
* Write Code for People (II) == Flow Control : @aronnem [75 min]

Day 2
* Don't Repeat Yourself == Functions & Modules : @aronnem [90 min]
* Plan for Mistakes == Testing : @katyhuff [75 min]
* Version Control == VC local : @gidden [90 min]
* Collaborate == VC remote : @gidden [75 min]

These are the proposed teaching assignments.  We hope that all instructors can frame their lessons in the context of the relevant "Best Practices" section.  We hope/expect that this will allow learners to make a better connection between the "how" and the "why".
