Remove app.set('port', port); in express generator 4

[superclarkk]

Setting the port, like, `app.set('port', port), is not supported in express 4, so should be removed.

Can you explain how is it not supported in Express 4? Settings are just a bag of whatever you want.

[superclarkk]

How is it utilised in the generated app? At the very least, it's superfluous.

It's just a very common convention to know what port your app is on to provide links in your layouts. Adding that makes {{port}} available in your layouts automatically, so you can do <a href="http://localhost:{{port}}/blah"> and it'll work for your development.

It was only added after tons and tons of requests for it; I'm not going to remove it and go through that again. If there is a PR you want to make to add more information to this line, or use it somewhere in the app, that would be accepted :)
