#11 History with charting

[Anonymous]

A new History plugin collects events for a list of periods.
On rendering, some js plotting (http://solutoire.com/plotr/) is used to report the monitor history as a graph.

- usage 1 : history is enabled with a large period (1 hour) and used to monitor how application envolves.
- usage 2 : history is enabld with a short period (1s) and the web ui is used as an instant view of application behaviour, for example just before some load-test is lauched.

An alterative is to use http://code.google.com/apis/chart/. This requires to be online, but this sounds acceptable.
