* Changed unsaved changes asterisk to an svg circle. #158
* Fixed#100
Unmatched routes are handled by react-router on the client side
and a single wildcard route on server.routes.js renders the index
html.
When the /:username/sketches route is matched and the username is not
valid, the user will be redirected to the index route and a toast
will explain what happened. When the username is 'p5' (default when
logged out) it will show all sketches. Maybe this should be changed
to just public or 'local' sketches?
