• [x] Donations -- rename Contributions. On the old Openness Project, none of the contributor names show -- it just says "none" -- but that will be fixed for the new site?
• [x] People -- rename campaigns, but keep the dropdown that has candidates and committees.
• [ ] Add "Financial Disclosures" -- which will open to the page with the explanatory information and links to google sheets.
• [x] Data Downloads -- let's just have the campaign data downloads here for now, since Financial Disclosure will have its own page. On the old site, the data ranges and different categories didn't work -- I recall just getting all the data every time. Which was ok. I think you could just make it where people download all the data. Once I see how the download works, I might suggest column heading clarifications.
• [x] Add a "Support" button to the right of About -- this will be a pitch for people to support this project through donations.

Adding "Financial Disclosures" to the header took up too much room, so i kept it under Data Downloads.

Filtering seems to be working find on Data Downloads, so I left that as is.
