Improve statistics

### Changed behaviour

After merging !46 (ref #9), we could improve the statistics page.

Suggestions:
- Add statistics about event attendance sorted by event type (from #389)
- Pizza chart. Showing percentages of everything > 5% with a max of 10 and everything else is 'other'
- Top 10 memberships of committees
- Percentage of active members compared to non-active members
- Bar chart with number of members per committees.
- Events heatmap with number of events per week

Also, some header on the page are unclear. As mentioned in #366.
