Set title to draft name

Would be nice to translate the unique URL to the html title

Kinda like...

https://demo.first-draft.xyz/d/Lorem%20ipsum%20dolor%20sit%20amet

<title>Lorem ipsum dolor sit amet</title>

Makes searching instances easier via browser history

Use:

• 1. draft title if not null or undefined (added in !40 (merged))

• 2. Use draft URI

• If creating a new draft, use slug unless generated slug for draft or new draft (once have draft configuration (#27))
