Count on answering a card, not on showing a question

[zjosua]

fixes #10

Description

Rating "Again" still counts as before.

A hook in Anki's Reviewer._answerCard would of course make this a lot simpler.

Really appreciate the help, thanks!

Will look into whether I can file a PR for that hook later.

Does this reduce the count upon undoing? I feel like it ought to, since most of my undos are undoing an accidental pass/fail and then immediately correcting it, but if the count isn't changed then every time that happens I'll be getting +2 for the price of one review.
