Typos / Miscellaneous Erata in Kindle Version about practicalnode

[SylvainBigonneau]

Here are some more:

• Introduction (location 333 of 8087) "there are there categories of programmers"
• Chapter 2 (location 1283 of 8087) "So far we've covered Expres.js installation."
• Chapter 2 (location 1369 of 8087) Is it just me or is the middleware code example more confusing than helping?

if (req.query.id) {
// process the id, then call next() when done
else if (req.query.author) {
// same approach as with id
else if (req.query.id && req.query.ref) {
// process when id and ref present
} else {
next();
}

Braces are opened but not closed, and the second else if never resolves to true since we already checked for req.query.id in the first if.
