Update support page

[sethetter]

The support page is out of date! Also the JS that was running there to pull our income / expenses is no longer working.

• Get rid of the fancy expense viewer thing.
• Put in a high level list of expenses?
• Keep the rest of the content -- recurring and one time donations, and referral codes (the Digital Ocean one seems to still work)

Other copy / style / formatting updates are also welcome!
