Update Express / Most middleware (like favicon) is no longer bundled with Express

[tnguyen42]

Hi,

I know that's an all project but you're still featured by Neo4J, so here I am 😄

When typing npm start after installing every packages and neo4j, this error occurs:

Most middleware (like favicon) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

I guess a little update is just required.

Thanks for the heads-up!

Sounds like we need to update this app to a newer Express.

I'll see when I can get time to get to this, but I've labeled this pull-requests-welcome in the meantime. =)
