* Add fuzzy search to /graph textarea We have a few thousands different metrics and looking up some of them can be quite annoying with the simple string matching. This patch adds a fuzzy search to the textarea lookup box on the /graph page. It uses a small neat library from github.com/mattyork/fuzzy. * Add fuzzy lib to NOTICE and re-build assets Previously built assets changed the mode.
