subscriber: "implementing FormatEvent" docs (#1727)

Browse Source 
This branch adds some documentation to the `FormatEvent` trait in
`tracing_subscriber::fmt` on how to write user-provided `FormatEvent`
implementations. There's probably room for additional improvement here,
but I just wanted to get something written down for now.

I also fixed a broken link I noticed while I was here.
