Looks like zci.answer should be printed whenever possible.

For `!ddg flip a coin` or `!ddg guid`, people had the excellent idea of **not** setting answer type to `E` (but `A`) so that we can't distinguish articles from some computed answers. _Real_ articles have no `zci.answer`, only `zci.abstract`/`zci.abstracttext`, so whenever possible, we should maybe just print `zci.answer`.
