Adding the rest of the past events into separate years.

I split the past events into years and added in the missing info for 2013 and 2012. 

##### Some things that need to be looked at:
* Harp freaked out on me when I used numbers for the year folder names so I wrote out the years. Someone who knows more should maybe switch those to numbers the right way?
* I just threw in some blue as the background color for the years nav. You can change that to whatever you think makes sense there.

Hope this works out.
