Mislav Marohnić cd2adfeba0 Port listing gists to githubv4 GraphQL client
- Fetching more than 100 gists is now supported
- The GraphQL query name is now `GistList` instead of `ListGists` for
  consistency with other queries
- Avoid fetching unnecessary Files fields
- Gists are now rendered in the order that the API returned them in
- The gist timestamp for machine-readable output is now rendered in
  RFC3339 format instead of in `time.Time.String()` format which is only
  meant for debugging and is not considered stable
- Ensure newlines in gist description are rendered as spaces
