I've split up the Media Viewer limn dashboard into a global one and one dashboard per pilot site. We'll shortly be adding more pilot site dashboards. For an up-to-date list of Media Viewer's limn dashboards, visit https://www.mediawiki.org/wiki/Multimedia/Metrics

Also in this update were new actions (no data yet since the change to record those actions just hit master) and key percentiles, following Nuria's recommendation, which I was able to generate with MariaDB thanks to a horrid trick described here: http://web.performancerasta.com/metrics-tips-calculating-95th-99th-or-any-percentile-with-single-mysql-query/
