First quick Sure rebrand (#74)

* First cut of smallest rebrand, pending icons

* Leave SQL schema tokens/user names the same for now

* First batch of logos

* Release notes/what's new

* /releases missing

* redirect_uri for sureapp://

* Padded logo

* Test the correct /releases URL

* Missed a few mobile URIs

* Some icons/asssets from /website/ repo

* Seed/sample data user @sure.local now

* New screenshot

* Want to keep their legal "boilerplate" from the upstream repo
