New conference timeline and concept map

It's nice to be able to have a full calendar as part of the timeline so the design team knows what they're supposed to be doing and when they're supposed to do it. The conference tag line and date are up on it as a constant reminder of what the conference is and what they're aiming for. This is important for team morale and motivation.

Doing this second iteration of the concept map in a square format enables visibility of relationships between artifacts. Each of these artifacts has either a practical, persuasive or poetic quality and is labelled either red (practical), blue (persuasive) or green (poetic). This also enables the design team to understand how the design of each artifact should behave and what the content should be like.
