Several changes as per Russ and Ian requests:
1. Fix almost broken ZoomIn/ZoomOut/Newer/Older with ability zoom in/out and move left/right w/o reloading (the 'explorer' attribute on graph).
2. Start the graph from the current release by default.
3. Allow to select the range of commits by specifying release range (e.g. go1.1 to go1.3 or go1.3 to tip).
4. Make it visually clear that you can select several benchmarks/metrics (replace select with a set of checkboxes).
5. Remove the "absolute" mode. Instead normalize all metrics to the start of the release (start becomes 1.0) and all subsequent changes are relative to it.

Currently for every benchmark/metric we show all changes for all builders x procs.
With 4 builders and 5 procs, that's 20 changes (20 red/green boxes in a single cell).
Instead show only maximum change for every benchmark/metric.
This significantly reduces clutter in UI.
When you click on the red/green box, you can see the rest of the changes.

Currently appspot logs say:
delay: gob encoding failed: gob: type build.PerfChange has no exported fields
And I was thinking why it is not sending mails...

This CL moves code from code.google.com/p/dvyukov-go-perf-dashboard,
which was previously reviewed.
