Added an optional options argument to the card component for situations where clicking a card to flip is not desired.

While using the card component in a project, I realized that there are situations where I don't want clicking the card to run flip() on it (for example, when putting a draggable map on top of a card I would constantly be flipping the card).

I noticed that the options argument in Card.prototype.render did not appear to be currently utilized, so I added a third optional argument when creating cards which is eventually passed to this function.

var card = ui.card('<p>Front</p>', '<p>Back</p>', {self_flip: false});

If the third argument is not included when a card is defined, the card will default to self_flip: true. I thought this was a good way to approach this in order to allow options to contain other single card-specific configuration settings should more come up in the future. Let me know your thoughts.

we could remove that default all together and just force the dev to decide how flipping is done

I actually like that idea even more

the use-case for having it auto-flippable is probably pretty slim haha. the doc one can still do that to demonstrate the API I guess

Were you thinking of removing self.flip() from Card.prototype.render completely and leaving it up to the dev to handle flip() in his/her own code?

The other thing with passing an options object as a third argument, it could be used to specify the flip direction, speed, etc. Lots of good optional info could be passed through this for when a dev wants to mix it up a bit.

premature for now since we dont have those, plus I like specifying those things via unique methods vs shoving large objects as an API
