Layout: Create Search component

Either implement this from scratch or find an NPM package to help.

• [ ] Auto-suggest streamers when you stop typing but before hitting enter.
• [ ] Redirect to streamer's page after hitting enter or clicking the result.

I'm not sure how possible auto-suggestion will be with the amount of streamers we'll be keeping in the database.
