group totals by week in model
Murry's aggregated_totals first-aid
tidy up views
sketch of dashboard
Add some unit tests for Total

Also make it normalize the total_on dates like Hit does.
Extract logic for rendering stack graph out of view

Some we extract into scopes and methods on the Total models, we expose that via WeeklyTotalData objects.  Some we extract into helper methods for rendering the charts.
dashboard bars
Fill in numbers properly on the little org dashboard widget
Add missing foreign key indexes to host and site
Make organisation dashboard box use real data
Optimize dashboard loading of all the orgs

We pre-loaded the counts for sites, hosts and mappings.
Tests for the bits we copied from hit to total
Move http_status_helper => http_status_categorization in lib/

So we can use it later in non-view areas and aren't tempted to add view-ish methods to it.
Use an OrganisationData object to hide the gnarly bits in the dashboard
Hide the max calculation too.
Fix failing integration test

The dashboard doesn't have the standard header/footer, so we use a different page to check people can log out.
Tidy broken HTML
smaller font
Parameterize dashboard/organisation view to hide metadata (dates, &c)
Add top 100 hits to org show page
