Merge lp:~jcsackett/charmworld/better-review-charting into lp:charmworld

[j.c.sackett]

Removes the min and max data from review and improves chart display.

This branch removes any display of min and max latency from the review queue.
The data is misleading to users, as they routinely mistake max for average,
causing communication errors between charm reviewers and charm authors.

Since min and max was added as a drive by addition, it's not necessary. The
easiest thing to do is just remove it from display. We continue to store it so
we have the data for analysis should we ever want it.

As a drive by, the d3 code to make the sparkline has been updated to make the
sparkline more legible.
