Issue #57: Set up Prettier

[jcfranco]

Sets up Prettier along with some NPM scripts to prettify™ all the things.

Once the config is reviewed and agreed upon, I'll format the source and include it in this PR.

My only comment is jsxBracketSameLine: false Gives you a lot of dangling > characters, but fundamentally it really doesn't matter. Thanks for setting this up 👍

Yeah all looks good, agree with @paulcpederson on bracket clutter, but, just preference. Thanks for adding. We could also put together a vs code settings gist with prettier-on-save, etc.

Moving forward w/ current config. A reason for jsxBracketSameLine is that it doesn't require messing with the closing angle bracket when making changes around the last attribute. We can always tweak it if needed.

After looking at results... maybe a little longer printWidth? Seems to break a lot of our top level imports to multiline which... is kind of noisy.

Obviously it just becomes a guessing game with an arbitrary length at some point... Ha

@macandcheese Could you create an issue to discuss potential tweaks? I'd like to get consensus on changes before re-purtyfying™.
