Adding a new document for tracking the slide decks associated with each talk

[nhuntwalker]

I've divided the document into the slides for Monday and Tuesday sessions. I also added space for lightning talks if there are slide decks that people want to have posted. Ideally, once we have the link to someone's slide deck we would update the document with their linked slides.

This is awesome, thanks @nhuntwalker.
