Now all builds done using the same commit hash are "grouped" in the graph. The 
main value (used for the main blue plot line) is the median value for all runs 
on that same commit, and then there is a minimum and a maximum line for those 
corresponding values. I'll continue to tweak the look to try out different 
things.

The graph gets a little busier this way, but this now allows us to add many 
more builds/commits into a single graph. There is going to be a maximum number 
of data points before it gets too crowded. I suspect the biggest drawback with 
this approach is if we update a dependency or something that changes 
performance. But that's not going to be too frequent and risks disturbing
graphs no matter what.

I also introduced an "alias" system for the commits, so that they can be 
refered to as C[number] on this page to make them readable in the graphs - and 
moved the labels to the X axis. I now also provide GitHub links for those 
commits at the top.

The moving average is now based on the main value from the 4 most recent 
commits. As we get more commits into the graph I'll try different numbers.
