resolves #45: new graphs

- regressions and recoveries: list of jobs whose run status changed,
  ordered first by currently failing jobs, secondly by count of jobs
  since the status change, descending for currently failing jobs and
  ascending for currently passing jobs
- low pass rates: list of the jobs with the worst pass rates calculated
  over all time
- run time changes: jobs with the largest changes in build time. This
  is calculated as the difference between the range and the standard
  deviation over the past 10 runs.
- average run time distribution: shows the number of jobs in the
  system divided into buckets based on their average runtime
