No error if connect is not defined

[bzuillsmith]

I forgot to npm install connect for my project and nothing was throwing errors when I used the app.use method. Might be nice to have at least a helpful warning if not an exception when use is not defined for connect but is being called.

if a non-function is passed to use() you should still get an error

No, I mean that I passed a good function to app.use(), but without Connect being installed, it didn't do anything and no error was thrown. As soon as I installed Connect, it worked fine.

when you install express connect is installed as well

Got it, thanks. Turns out I was using some deprecated code. Lot's of old stuff out there in guides and docs that aren't true anymore!
