Gulp Chapter Updates (Server, typos, etc.)

Very sorry for the delay. I've been swamped at work, and I've been meaning to get back to work on this for quite some time.

Rewrote the server task and cleaned up what typos and mistakes I could find. I actually don't use gulp to spin up a server very often in my normal workflow, so please check the code for accuracy and please let me know if there are ways to improve on it.

I'm considering replacing the LiveReload section with BrowserSync, but I figured I would let the rest if the contribs help decide what is best.

Thanks everyone!
