show grain method invocation activity per grain type (across all methods) on dashboard home page

[danvanderboom]

The Orleans home page has two sections: "Grains" with a chart showing number of grain activations over time, and "Silos" with a chart of the number of silos over time.

For each grain type listed, display a short chart of the number of grain method invocations over time for each grain type: the total number of grain method invocations, regardless of which grain method was called.

There is a summary of all activity on the dashboard home.

There isn't currently a breakdown by grain type, this might be a bit of an overload?
