Upgraded brick to 1.0.0rc1

I had to:

* `s/shuffleTo/showCard/`
* `s/shuffleNext/nextCard/`
* `s/shufflePrev/previousCard/`
* Backfill in some styles they removed for `x-appbar` and `x-appbar header`

The header is slightly taller and has better contrast (white font instead of gray). Other than that everything should look the same.

We need to make sure we test on devices and all that. I have only tested on desktop so far.
