Support the statistics gathering for the churn graph 

I'm still somewhat uncertain about how I want to create the graphs, I may need to add historgram support to CairoPlot to do precisely what I want:

			|
			|  |+++|
			|  |+++|
			|  |///|        ___
			|  |///|       |+++| <-- avg added per commit
			|  |///|       |+++|
			|__|///|_______|///|_<-- avg removed per commit
			  [tyler]     [other]

Uncertainly, BAH.
