The user activity chart stems from before most sliding windows and aggregation methods were switched from 30-day intervals to 4-week intervals. The benefit of this is that weekends are evened out, which avoids accidentally misinterpreting some fluctuations.
This changes the user activity chart accordingly for consistency.
Additionally, the time range computation in the updater report receives a minor refactoring based on the more recent reports.
Note that this change will invalidate previously recorded data based on 30-day intervals. However, no action is taken, because the difference between data aggregated over 28 and 30 days is expected to be subtle.
Resolves #129.
