Modify card search functionnality to add mutliple results

[LeCodex]

When searching for a card, I think it could be better to first see a list of potential results, from which you could then pick with a button, reaction, or simple message.

The list could appear only if the fuzzy search isn't sure enough of the first result, which would most likely happen if you searched for a vague term like "Temple"

I'd accept a PR that does it. I already do this with !rules, so creating a copy of that should be somewhat straightforward.
