Added speakers & sponsors, cleaned up layout, fixed poorly calculated schedule times

- Added Rich Robinson & Garren DiPasquale to the speakers roster
- Added missing sponsor logos
- Cleaned up layout silliness going on with the site in general. Added a bit more separation in the level of sponsorship.
- Added a max-width on the homepage. Long text is long. Still need to adjust some HTML & CSS for other pieces of the site so the CSS isn't so redundant
- Fixed the session times because...math is hard.
