Tiny fixes collected while reading through the Rust book. If they're too nitpicky please let me know and I'll ignore the next ones. :)
The spaces after the function and closure arguments might be intentional, but they do not make much sense: the usual formatting doesn't have such spaces, and they aren't helping align the three lines together either.

This PR fixes two little typos in the Dining Philosophers example.
Also, there are two style points that may have been oversights but may have been deliberate, so I'll just bring them up here:
1) In the last paragraph, you say
> You’ll notice we can introduce a new binding to `table` here, and it will shadow the old one. This is often used so that you don’t need to come up with two unique names.
You already said something similar to this in the Guessing Game, but maybe you intended for this example to be independent of that one.
2) In "Rust Inside Other Languages," you introduce the idea of the "global interpreter lock" and then refer to it as the GIL a few paragraphs later without explicitly stating that GIL == global interpreter lock. It's reasonable to expect readers to make the connection, but maybe that's not what you intended.
Excellent work on the examples! Congrats on 1.0!

The Traits chapter uses "adding methods to `int`" as an example of "something bad", but there is no such thing as `int` anymore, right? So I changed it to `i32`.
The download links of Windows installers on the Nightly Rust page are using beta builds instead of nightly builds, which caused some confusions when I was setting up my env. Probably it's better to use the links of nightly builds here.

I fixed the typo of the value of e in the memory tables. It is a reference to d, and so it should contain the memory location of d. I also fixed the incorrectly formatted tables so they display properly in html pages.
