styles charts and stuff

- Styles Revenue Donut, Facilities Donut,  Revenue Area, and Crime Bar Charts.
- Makes charts responsive

In a separate PR I would like to ...
- Create custom tooltips
- Fix mobile chart dimensions
- Make colors consistent
- Move most of styling out of CSS 
When reviewing files to add, don't add files that only have white space changes. Undo their changes with `git checkout [file]`.
Not super important, but best practice for future pull requests.
